What is the standard for tipping when picking up Take Away at places like Carrabba's and Outback? I gave 15 percent at Outback but am at a loss for Carrabba's which I walk up to (being I am about 100 feet away -- staying at a Residence Inn-type place).
So, should I leave anything? 10 percent? 15 percent? I mean what am I tipping for? Them putting my food in a bag?
