You’re an asshole when you come into the store 10 minutes before close, browse until 10 minutes after close, and then demand coupons and other discounts when you’re checking out.
Oh, and because you wanted to save that extra 15% and apply for the shopping card, it doesn’t entitle you to behave like an asshat when the purchase is applied to that card instead of the card you wanted to pay with, especially when you were told this little tidbit three times before you actually applied.
Finally, it’s not polite to passive-aggressively insult the person who’s doing her best to assist you while navigating through your asshattery. It just makes you look like a cheap bastard.
Thank you.
