Right off the bat, be forewarned Marc's only accepts the Discover card. So they have not progressed since they first opened. Really this is a major pain in the ass. The ATM steals something like $2.50 to give you your own money.
The store is poorly laid out with too tight aisles. It's dirty. The staff is about as oblivious as possible. Seriously I have never had one greet me or even smile. The cashiers obviously hate their jobs and I don't blame them since they have long lines and have to bag everything too.
