My question is why are Mondays and Tuesdays slow and what would counter that?

Secondly I take my son to a hobby/train shop in a town near us, the shop owner keeps a ridiculous schedule, once we went down there and it was close on a weekday because it was mothers day(sign on the door)! We were side by side by side with other people wondering what the hell? Then he was closed on Mondays, now it's Sundays, and now it's F him! Now I take my kid 15 miles more out of the way to a different shop.

Stay the course is my advise as a consumer.
