After dealing with movers, cable guys, couch guys, wall building guys, and every other service guy imaginable, I had an idea for a side project for you. Also, this may exist already, haven’t looked yet. But it’s a site where you plug in what the service was, how much it cost, how long it took, how happy you were, variables like that, and it spits back out how much to tip the service guys. I don’t know if data like this even exists but it would be very HANDY (get it? ;) ) Just food for thought.
