A friend of mine works there and gets paid £6.50 per hour. It might seem low but the hotels etc in the area pay min wage so they are much better in that respect. The only difference being the number of hours on offer. They work one day a week if that - but love it!
I don't have problems when oredering food or drink at the Amex - I spoke to one of the Kiosk staff after half time a few matches ago, yes, a student. Her insight to it all was that yes, of course there were a lot of Students working at the stadium as no one else really wants a job that is 1 day...
