I got takeout lunch today for the office from a place I don't usually pick up from (someone else does). The staff are good, hard-working women with a great attitude and provide good service. There is a tip jar at the register, which I intended to contribute to. So one woman rings up my sale, I pay her, and she gives me the change, then turns away to tend to other duties. The other women were all busy taking care of other customers, so not nearby. I wanted to give a tip, but I wanted her to KNOW that I was giving a tip, because in addition to it being the right thing to do, I think it generates good will. So of course I put the money in the tip jar, but I was disappointed that no one saw me do so. I actually thought about waiting until she turned around but thought better of it. She didn't turn back to the register for at least a minute or two, which would have been a ridiculous amount of time to wait. (I paid in advance so that I could take the food as soon as it came out, so I was waiting anyway.)
So my question to you all is, would you have waited? Or do you think it's irrelevant whether someone knows you've tipped them?
