So... I just found something out that confused me. We have gratuity already worked into the per person price of our contract, but we still need to add on tax. So I asked our contact how tax is calculated if gratuity is also included (since we shouldn't pay tax on gratuity) and her response was: "Tax is calculated on the per person price because our servers are not paid a gratuity; they are paid a higher hourly wage."
Has anyone else experienced this? I find it a little weird and now feel badly. Part of why we picked this place was that gratuity was included. Now do I have to give them a tip on top of what we're paying? I think it's sorta BS that the servers don't get gratuity. Though I guess they also don't lose out if someone doesn't tip. (But a higher pay could be $8/hr instead of $3/hr or whatever the special minimum wage is for servers these days.)
