my man doesn't tip restaurants

I never like to stiff anybody. I overtip most of the time. I think I have posted about this before. What I don't like is when I see tip jars at a pizza place or bagel place where I feel like I am compelled to give a tip to somebody for taking a couple of slices of pizza and putting it on a plate. Or taking a bagel and putting it in a bag. That I don't like. Next thing we'll be seeing a tip jar at a supermarket or 7 eleven where people are throwing money in a jar because some guy ringed up a can of soda for you.
