Old "freshly squeezed orange juice"!!

I purchased a "freshly squeezed orange juice" from the Gateway kiosk / coffee shop. After paying for it, I noticed that there was no expiry date on the bottle. I queried it with the person serviing me and I got a blank stare back at me - no clue what I was talking about. I then went to customer service, they proceded to go to the deli and stick todays date on the bottle - when I said to them that this bottle could have been lying here for a week - they ignored me. I got back home (25 kms away) and opened the bottle and lo and behold, the bottle hissed and the juice was completely sour. Thanks Checkers
