Same here.

One of my first customers was a tree service. They do all their maintenance on the weekends to keep their crews running during the week. When that call comes I show up.

Also if it's scheduled in advance I've been known to schedule things on a Sunday just to avoid traffic and get parking. (Downtown Tampa or St Pete)

Airgas sucks. I actually go out of my way and pay a little more to a mom and pop in my area (Crumpton Welding supply).
