You realize that your Gym, not Groupon, decided to issue too many coupons that resulted in the hypothetical crowding situation? That is your Gym's fault.

I actually don't know if that's true or not - do businesses set the number of Groupons available by themselves? I doubt it.

My understanding is that Groupon allows them to set a limit.

Yes, I've read that businesses can set a limit. However, a low limit might discourage Groupon from running their deal.
