I was in Rome a few years ago for Italy v England in the 6 Nations.
They had beer wallahs walking up and down the steps to save you going to the bar. As it (Stadio Olympico) is primarily a football ground they'd been told to pour the beer from the cans into the waiting plastic glasses. The bloke on duty near us got bored and just started passing out 4 packs. Nothing got thrown, it and we got drunk. They had great big perspex screens separating sections of the crowd - presumably to stop me giving some Italian fella a cuddle at half time? I went out with an England flag and came home with an Italian one. Cracking day out, never a hint of trouble. Football fans are (largely) an embarrassment.
