Input: My best friend owns a successful plumbing company and sent one of his employees to service my navien on demand hot water and furnace. The bill was  382$ for 1.75 hrs of work. I guess the part that bothers me is that I’ve spent countless hours the last two summers helping him reno his house and then helping him reno his back patio.  Obviously I wouldn’t expected to be paid for helping him reno but kinda assumed it’s a I’ll scratch your back you scratch mine kind of thing. After renoing his house I bought a house and wanted to redo the plumbing, he showed up for a grand total of three days and then stopped showing up and sent an employee that I had to pay. I wasn’t really impressed because I had spent so much time helping him. (on and off for three months atleast a couple days a week)

I’m all for supporting a friends business but I’m starting to feel a little shafted. I was assuming that he would just send a bill for his employees hrs at his hourly rate, not his marked up contractor pricing. So am I the asshole for expecting a deal and should I say something or should I just shut up and pay it and never help him again when he asks? Also I attached the bill and I know he pays this employee 28$ an hr
