Agreed. I pretty much tip all of the people on that chart except for dry cleaners and I'm just finding out housekeeping. Are most guys tipping housekeeping?

I always tip the van driver unless they were super terrible (really late generally) and most times I tip even then.

For the guys that say they don't carry cash, I have two solutions. 1) when I go to the grocery store I use the self checkout and get $4 back, if you go twice, $8 is enough for a trip. Also, I went to the bank and got a $100 of $1's, those are in my watch box, when I get out my work watch, I take out however many 1's I need if I haven't been to the grocery store.

I agree with the Baradium, you don't forget socks, you shouldn't forget tip money.

If you just want to be a cheap jerk, that's fine, you do you, but at least own it, "I forgot to get cash" is a lame excuse.
