@edgarblythe,
In that case, I'd probably tip her. But definitely NOT at the same rate as someone who took my order and brought it to my table.
I hate it when I go in counter service restaurants and see tip jars at the counter or next to the register. I have a lot of respect for good waiters and waitresses...that was my first real job...and they deserve to be tipped well. But I think it's ridiculous for every place that serves food to think they automatically deserve to be tipped. In particular, if I have to get my own silverware, drinks, napkins, etc., and carry my own food to a table, I think the tip belongs in my pocket.
