Don't get in a HURRY!

One time I was painting a car and had told the wife I would be ready to go soon as we were having dinner with her family that evening, well one beer led to another and well now the rush was on so I mixed the clear coat and spayed on coat one and cracked open another beer while waiting for it to tack up, then it was time for coat two and when I was refilling the gun I noticed that the activater was unopened!!! To this day I wonder was it the fact that I was in a hurry or was it the BEER???
