So, we're having some work done on our house because we're moving and want to make sure it's in decent shape for tenants. Today we had a grout and caulking guy over. The job was $780. I noticed my wife had taken $60 out of my wallet as she was writing the check. I quickly took the money from the table and put it back in my wallet. She just gave me a stare and gave the guy his check. She was upset with me after he left saying she wanted to give the guy the $60 as a tip. I told her we would go broke tipping all the contractors like that. I'm questioning how many other people tip contractors like that? I swear, it just seems like we've become a tip happy society. At what point did it become necessary to tip people for doing their job?
