If the store is close I sure would.
The pet store isn't that close but I can take two public busses to get there in about an hour. It's not a big deal if I do part time on the days I have off from my full time job. I defnitely could not work right after my full time during the week.
I'm on my feet all day at my full time job, too. In my previous position, we had ergonomic mats to stand on. Maybe that is something you could use in your job? I can't use ergonomic mats in my current position so there are days when my lower left leg and foot feels like a lead weight
One of the biggest problems with my job is that at the end of the day, my feet hurt. They throb, they swell--and it's painful. One of the first things I got with my paycheck (aside from a belt that isn't plastic and another pair of pants) was a pair of a gel insoles--with arch support. I strongly suspect that my arches were falling down--and I only say that because of how painful my feet were before and how they hurt (in a different way) after the arch support was put in the shoes. Is there any way, other than elevation or ice water (which makes the muscles in my feet cramp until my feet are in strange positions and I have to flatten them against the floor) to get the swelling down and control the pain at the end of the day?
