McDonald's

I stopped to get a Sweet Tea before getting on the freeway. The dining area dispenser was out. I told the cashier and she was going to get me some from the drive thru dispenser but that one was empty also. Probably just a rush on tea as it was a nice day, but its all I wanted to get and didn't want to wait for them to brew more. Got my $1 back and drove on. Better planning/checking supplies would be helpful.
