Yes it does but think about it. The bike shop you are talking about picked the slowest day for then how? Flipping a coin? I doubt it. I believe the owner saw an advantage to being open a different day because there was a customer base on Sunday they didn't have on Tuesday. I don't think they we stupid for picking that day. So if someone came in and said, hey I ride my bike onve a month on Tuesdays what isn't that bike shop open on Tuesdays someone like you or the owner would say? "Because I felt that was the best day to be closed. End of story.

But here is some questions a owner has to ask. Will I receive ordered parts on Sunday? Can I order parts of Sunday? Who are my best paying customers? When do they come in to buy or order parts? UPS and Fed Ex don't deliver on Sunday nor does USPS. The factory order desk is closed Sunday. So for someone like me being open on Sunday does absolutly no good. If I go in to order they can't order till Monday. If they get me next day delivery I can't pick it up till Wednesday. So my LBS knows their customers and what days work best for them. Just like your LBS knows his customers even if it isn't the same as the one I go to. So theanswer to the origional question is, the bike shop is closed on Sunday because that was the best day to be closed according to the man that took money out of his bank account and bought the store. End of story. If I lived where you do and my shop was closed on Tuesday more than likely I would find another shop because I don't want to wait three days for ordered parts of supplies. And because there are two other shops open within 3 miles of me on Tuesday it would be easy to do. I have a road bike, a MTB and a Simi recumbent I bought from the same shop and I have fewer bikes than most of our club. I say again, the person most qualified to decide what day to be open is the owner of the LBS the OP has a question about.
