Honestly guys most ladies would rather you tip them the extra money rather then buying a gift. Tell them to go buy something nice for yourself. I wouldn't buy chocolates, I have been offered to help myself from a few boxes of chocolates her other customers have purchased for her as a gift. Even offered the entire box more than once. They won't tell you to your face they don't like them. Ask what kind of food she likes. I got a lot of mileage from a trip to 5 guys burgers of course I bought 6 burgers and a double order of fries. Of course I found out ahead of time they really liked 5 guys.
