I used to play for fun when travelling with my son on my many trips with him from a few years ago but not for money I may add.

OT but as you mention a vice I don't really think gambling is overall a bad thing if done in moderation which it mostly is plus it is a huge employer.

My old Dad who in his mid 80's widowed and still relatively fit enjoys a wee flutter as many of the population do.Talking £5-6 here, a few times a week and is a regular at his local bookmakers. He enjoys it but not only from watching the races but from the walking there and the social interaction he has with a few buddy's there which fills his day as I suspect it does for many others. Plus, his carbon footprint is so much better than us BA flyers which is arguably a lot worse than gambling but appreciate a necessity for folks flying for work.
