I understand that it costs $1 to rent any type of racquet. Last week, my friend rented 2 racquets for racquetball by mistake (we were going to play badminton). He asked a member services staff if he could change it for a badminton racquet right after without any extra charges, but this was to no avail. The "system" would not allow it (the staff was nice though). I suggest charging members $1 for racquet rentals while giving members the privilege to switch types of racquets throughout the day. Else, giving members a grace period to switch racquets in case of mistakes like my friend's would be nice too.
