| Comment | What I meant was that the difference between the 5% and the 25% is mostly going to be due to the fact that - according to the poll - most people tip some of the time rather than always/never
e.g. if never/rarely/sometimes/often/always corresponds to tipping 0%/25%/50%/75%/100% of the time, and the proportions in the poll are correct, then we would expect the average rate of tipping - as witnessed by a member of waiting staff - to be about 60%
So if anything it's the other way round - the poll under-predicts tipping rates compared to what raging-big-fart says. Which might be explained by the opposite of what you said - that it's likely people who tip more go out more. |
