Easter weekend bunny costumes

According to my count, I have eleven bunny costumes for Easter. It seems like that everyone wants to have the deluxe edition even when they know it gets too hot. Probably just because of the name. A lot of people also consider their costume booking for bunny suits urgent with no regard for other urgent bookings by other people. This selfish behaviour causes me some problems if they decide to not return the costume on time or to collect too early. With the too early part they at least cannot get it if it is still out. What does not help is if people just do not bother reading the opening hours and just assume the opening times.
