Plumber billing question
Just had a plumber here to fix the toilet. The fill tube broke off the overflow tube, and the whole valve needed to be replaced. He said it was an older style that he didn't have in his van, so he had to run out and get it. He was gone about an hour and then came back and did the job in 1/2 hour. He charged me for the whole 2 hours at $65/hr and $35 for parts.
Is it typical for a plumber to charge the customer for time spent to run out and get parts he doesn't have on hand?
