This is the second time in a row i've gotten carryout and they simply handed me by box and said "bai!" instead of printing out a receipt with a section for a tip forcing me to think quick and have the balls to put zero dollars on a pickup order or fall for their trick and give them extra money for no damn reason.
Most places have automatic gratuity for carryout now. Try ordering in once. Then order carry out to find out the % of gratuity they charge for delivery. You'll find out that the tip is already included in the price for delivery
What tast519 said. I do tip though at restaurants on orders where they take it to my car/ deliveries though. I'm not tipping if I have to drive there then go inside and get it lol! Screw that.
