Someone promised to help me with some welding on my car and would come and do it last week.
No-show, so I called him and he said he would do it yesterday instead. I went over in the morning and confirmed we were OK for the afternoon.
No-show, so I called and he said he'd be here at 10 this morning.
No-show. Now, we had a little snow but nothing that has affected travel or even the phones but I've heard nothing.

If I get someone else and pay them to come and do the job, should I be bothered if he is upset?
