Thoughts provoked

Received via email "We enter a little coffeehouse with a friend of mine and give our order. While we're approaching our table two people come in and they go to the counter. ' Five coffees,  please. Two of them for us and three suspended' They pay for their order, take the two and leave. I ask my friend: 'What are those 'suspended' coffees?' 'Wait for it and you will see' Some more people enter. Two girls ask for one coffee each, pay and go. The next order was for seven coffees and it was made by three lawyers - three for them and four 'suspended'. While I still wonder what's the deal with those 'suspended' coffees I enjoy the sunny weather and the beautiful view towards the square in front of the café. Suddenly a man dressed in shabby clothes who looks like a beggar comes in through the door and kindly asks 'Do you have a suspended coffee ?' It's simple - people pay in advance for a coffee meant for someone
