Let's be accurate: I ran out not as the check was being presented but as you made the following announcement:

"We're going to divide the responsibility for this. Bruce will determine how much each person should pay. I will collect the money. Dovster will pay the bill."

I understand that as a result of this arrangement, you made a profit on the trip -- despite buying an "A" fare ticket and Traveller, who volunteered to take my place, had to put off buying her new condo until November.
