I hate loose, aggro players and try not to get involved with them without a hand. Pocket eights are good shorthanded, I would have raised preflop to let him know I have a hand I'm willing to play. If you are only playing strong hands against loose aggro players, you will either bust them, or they'll give you respect when you play-back at them.
What was the final result? Why such a large pre-flop bet, was 5x the big blind a standard opening bet in that game?
