Just a quick request to comic shop owners: if your hours are posted on the internet, and they match the hours posted on the door of your shop, you might do your best to be open during those hours. Because someone might have taken a half-hour subway ride to try and spend money at your shop, been disappointed and annoyed at his inability to do so, and ended up spending that money at a big chain bookstore instead.
I mean, that can’t be the preferred outcome for you, can it?
