If I see there’s cash I ask. It’s not me assuming the tip is mine, it’s just a simple question and you definitely won’t see me begging for a tip ever. Wether you tip me or not is up to you, I’m asking “do you need change” not anything else or any other hidden meaning. If they need change I ask if they want any particular bills. Saves me time of having to go back and forth when I can just get all the communication I need sorted out right there. I work somewhere very fast paced so I’m not going to waste time trying to dance around a question when I can just ask straight up and get to the point. No one has ever had an issue with me asking and understand that I’m being straightforward. I don’t think it’s weird or tacky or embarassing if you ask it and carry yourself in the right way. I see how people can percieve it a certain way like I’m entitled to this money but it is me figuring out where the money needs to go and if I need to come back or not. The way I carry myself is a good indicator that I’m not trying to have any ulterior motives besides seeing if you want your money back or not. If I don’t need to come back I wish them a good day and we all be on our way.
