Happened a year ago but still feel bad about it...I was on a flight from JFK to ATL and sitting next to an elegantly dressed gentleman. Got a glass full of orange juice but put it aside as I continued to work on my laptop. Wanted to reach for my juice minutes later, but somehow succeeded in pushing the glass to the gentleman next to me. He pant were all wet, but he remained very calm, rushed to the toilet to clean up. Could not bear sitting to him the rest of the flight.
