First off, you are not shopping at a big box store.  You are shopping at a members only club.  One that your Dad is a member of and agreed to the rules thereof.  If you don't like it, either don't shop there or get your own membership.  If this had been a regular store open to the general public, I'd agree with you somewhat more.  Also, if you're all up on Remembrance Day, due to your father being a vet, what the heck are you doing shopping instead of remembering (at least until 11am)?
