Went out with some friends last night for MNF and when the bill came we got in a discussion about whether the tip should be applied on the pre-tax or the post-tax amount?
What is your take?
I never even considered tipping on the post-tax amount. I think you should only tip on the goods and services you received and not the amount the government imposes upon you. I usually just double the tax and adjust from there (usually up), since tax here in Buffalo is 8.75%.
