Do some eateries serve bigger portions to customers, who previously tipped?
There's this one eatery i went to eat out many times in the past and previously I have tipped some money (not little, not much, just a generic tipping amount) after I finished eating. I did that more than 3 times now.
Today I went there again to eat out and I noticed I was served bigger portions than usual.
Do some eateries actually do that to tipping customers, who keep coming back from time to time?
