I'm aware of the concept of confirmation bias but when I worked in hospitality I hated rugby weekends. The French and Italians were fine, the Irish and Welsh were pests with a drink but ultimately harmless.
The Scottish fans fell into 2 camps. You had the borders guys who were real rugby lads and enjoyed a drink but generally behaved well and had a good time. The more stereotypical Edinburgh merchant school type was a different matter and they had a lot of similarities with the English fans in that they treated you, the property and especially the women working like crap. Boorish, arrogant and rude. Pint glasses full of piss was basically seen as acceptable, slightly more frowned upon but still 'just a laugh' was the 'who can do the biggest ***** in a glass' competition. We dealt with multiple complaints from female customers and staff about being groped or often lifted completely off the ground and passed around like a trophy. It was a ****ing nightmare. I think part of the problem was they were used to drinking in their own rugby clubs were than behavior might be accepted as a bit nore harmless than a public hotel or bar.
Worst of all was the complete indulgence of it by the senior managers because 'they spend a lot of money'. Every year during the 6 Nations I'm thankful I'm out of the industry.
