this didnt happen to me, but a lady on one of my flights couldnt get the lid off the orange juice. man, she was trying so hard to get it off haha. and when she did the juiced went flying out of the container, onto chairs and pax. she couldnt stop apologising.
On a narrowbody United flight, the guy in the aisle seat next to me asked for a 7-Up when the drinks trolley came round. The can must have been rolling around in the cart as when the lady opened it, she got the 'fountain' effect and covered the poor guy. she was mortified and couldn't stop apologising. After getting some towels to help him clean up, she came back a number of times to offer him anything on the trolley free of charge. He saw the funny side, though.
