As the turnover of staff is so high then having extensive training/induction programmes wouldn't make sense. And as trained bar staff aren't necessarily likely to pick the 20 game a season option of working at the Albion once or twice a week then you're left with unskilled students etc who won't have had 150 HOURS or so.
I've been to over 70 odd matches at the Amex now and i've never once had the wrong pie, a bad pint, or (really) bad service. A little bit of confusion from time to time but thats it. I've just had to stand in a queue for 5-10 mins max.
What stand are you in Jem?
