Instant result
Plain-English why
Copyable takeaway
What this means
No waffle. Just the number and how it was worked out.
Formula used
Context-based expectation check, adjusted for service quality and prompt method.
Worked example
Counter service at a coffee shop, device turned toward you with a 20% default, service was fine — verdict: optional. The norm does not exist here; tip if you choose to.
Common questions
Am I obligated to tip at counter service?
No. Counter service tipping became common as point-of-sale systems added tip prompts, not because there was an existing social norm. For exceptional service, it is a nice gesture. It is not an obligation.
What about self-checkout kiosks asking for a tip?
There is no established basis for tipping at a self-checkout. You did the work. Declining is entirely reasonable.
