When team building attacks!

We're all reeling from an event last night for a client who will remain anonymous. It was an event for trainees for a large financial. They were all men and sometimes these events can be a bit boisterous. It was an evening event and by the time they all arrived with us they had clearly had a skinfull and then they proceeded to drink heavily for the rest of the evening. By the time the events came round many of them were reeling on their feet. One of our older chaps was dressed in the chilli costume and for some reason they decided to try to remove his underpants. It was schoolboy prank style wedgies I think, but it still left our poor chap rather shaken. We had an attractive female instructor working and she had a lot of trouble. Most companies use drinking as part of their team building and I agree that this can work but sometimes it just goes too far. When they are that drunk I really don't think they care about the events; our priority then becomes damage limitation and making sure our own staff are safe. I understand the venue was trashed as well. Some companies need to be a bit more careful about the culture they promote.
