10 problems that cost restaurants repeat customers.

Updated 1 October 2026 · 6 minute read

The ten issues that show up most often in consumer research and complaint data, each with the evidence behind it, a practical first fix, and our guide to fixing it on Just Eat, Deliveroo and Uber Eats. Written for UK operators.

In short: customers stop re-ordering when food is slow, cold, wrong or poor value, when service or hygiene feels untrustworthy, and when reviews go unanswered. On the delivery apps those same problems show up as low ratings, which push you down the restaurant list. The fixes below are mostly free: packaging, prep times, order checks, menu descriptions and replying to reviews.

The ten problems

  1. Customers are eating out less (price sensitivity)
  2. High staff turnover destabilises service and quality
  3. Long waits and slow service are a top irritation
  4. Rude or unhelpful staff kills repeat business
  5. Food arriving cold undermines ratings and re-orders
  6. Wrong items and missing items trigger refunds and bad reviews
  7. Hygiene ratings influence where people buy food
  8. Not responding to reviews materially hurts conversion
  9. Portion size mismatch creates waste and “not worth it” sentiment
  10. Repeat guests drive the majority of revenue
1) Demand pressure

Customers are eating out less (price sensitivity)

Evidence: A YouGov poll reported 38% of Britons were dining out less than a year earlier, with higher costs the main reason for cutting back.

First fix: Tighten your “value story” (best-sellers + bundles) and make your hero items impossible to miss.

2) Staffing

High staff turnover destabilises service and quality

Evidence: Workforce data analysis for 2024 reported hospitality/catering staff turnover at 38.7%.

First fix: Standardise the basics (opening/closing checklists + station SOPs) so performance doesn’t depend on who’s on shift.

3) Speed

Long waits and slow service are a top irritation

Evidence: A UK consumer study found 34% said long wait times were the thing that annoys them most when dining out.

First fix: Track ticket time by daypart; fix the single biggest bottleneck (usually pass, fryer, or drinks).

4) Service quality

Rude or unhelpful staff kills repeat business

Evidence: In the same UK study, 30% said rude or unhelpful staff was their biggest gripe.

First fix: Write a simple service standard: greet, confirm order, set expectations, and close with a check-back.

5) Delivery quality

Food arriving cold undermines ratings and re-orders

Evidence: A UK survey of 2,000 people commissioned by Supper London reported 48% of delivery orders arrived at an unacceptable temperature.

First fix: Heat retention: vented lids for fried items, separate hot/cold bags, and “hold time” limits before handoff.

6) Accuracy

Wrong items and missing items trigger refunds and bad reviews

Evidence: The same Supper London survey reported 30% of people had received the wrong order.

First fix: “Two-point check”: packer verifies ticket + runner verifies bag before sealing.

7) Hygiene trust

Hygiene ratings influence where people buy food

Evidence: Food Standards Agency survey results show around 42% checked a food business hygiene rating in the last 12 months (Wave 8, Oct 2023–Jan 2024).

First fix: Make hygiene visible: display your rating, cleanliness routines, and “what we changed” after inspections.

8) Reviews

Not responding to reviews materially hurts conversion

Evidence: BrightLocal’s Local Consumer Review Survey 2024 found 88% would use a business that replies to all reviews, versus 47% for one that doesn’t respond.

First fix: Reply to every review for 30 days. Keep it short, specific, and consistent — and fix the recurring complaint theme.

9) Value perception

Portion size mismatch creates waste and “not worth it” sentiment

Evidence: WRAP research found 48% of people say portion size is the main reason they leave food when eating out.

First fix: Align portions with price: make “small/regular/large” explicit for key items, and tighten plating consistency.

10) Retention

Repeat guests drive the majority of revenue

Evidence: Olo (based on 100M+ guest records) reported 60% of restaurant revenue is driven by repeat guests.

First fix: Build a simple “reason to return” within 7 days: loyalty perk, bounceback offer, or signature item hook.
