Was out mowing yesterday, there was a moving van across from one of my accounts. The guy moving in comes over and asks how much to mow his yard one time, as he doesn't have time right now. I had the time so I looked it over and quoted him $35. He instantly says "I'll give you $50, you're doing me a big favor". I said "works for me". And with that he pulls $50 out of his pocket and pays me, before I even mowed. I've had lots of people say "how about $30?", but this was the first time someone has ever offered more. The world needs more people like this guy!
