I live in a traditional stag do area. Many times that I've gone on nights out, I bump into a stag do.
They are usually loud and they go round talking to every woman in the bar. Some of it is innocent- we are on a stag do, we are having fun. However I've seen a lot of crap behaviour.
I always try and avoid them because the men on stag dos are so annoying.
I don't think I'd trust any man on a stag do. They see it as a great time for fun. That includes women.
The last stag do I had the misfortune of bumping into went like this. One of the man came over to me and said "yayyy we are on a stag do". And he pointed out the groom. I went back to looking at my drink.
The groom then came over and I said to him politely"oh are you the one getting married, congratulations".
He said to me " well the wedding is pencilled in, I'm keeping my options open".
Then I saw him later kissing a woman at the bar.
I don't think stag parties are ever a good idea!
