I usually tip a few bucks when I place a pick up order, but it's not usually 15%-18% like I'd normally tip for table service. I figure someone did sort of "serve" it to me.... pack it up in box(es), put in napkins, utensils, etc. I don't know how they split up the money, but I usually kick in a few bucks when I'm ordering for personal use.
Since it's a shop and it says to tip 15% minimum, that's what I'd do. I'd probably use my phone calculator and tip exactly 15% based on the pretax amount.
If they have a tip jar, put it there. Otherwise, hand it to whomever hands you your order. Unless the instructions clarify this somewhere?
In general, servers make below minimum wage so depend on tips. The cashier at many wing places, where they have sit down service, is probably a server. I had a friend that tipped everyone, even at food trucks. Starbucks and Five Guys have tip jars. Tipping is a very nice thing to do when ordering take-out. On the other hand, they are more likely to remember you. That could be either good or bad.
Hey Cecilia...Just letting you know as you have said you are new. It is great to tip more for great service out of your pocket but before doing so, be sure to check the guidelines. There are some guidelines that will prohibit doing so as it could out you as a shopper (some people think that since they are getting money for eating that they reward the server).
