How do Arsenal get away with charging £4 for a pie? Is it better quality than those sold in other stadia? Is there perhaps, some meat in it? Looking at the list of prices to attend a football match these days I am glad I passed my season ticket on to my son, way back in 1980... By the way I can remember when members of Her Majesty's forces could get half price admission to matches. That was during and for a short period after WW2 of course, I used to wear my army cadet uniform (Liverpool Scottish) uniform and get in for 10 old pence.
In my experience the pies, burgers, hotdogs etc available at sporting venues are the cheapest and lowest quality available and imaginable. Served with the sloppiest of poor standards to people that think that's all OK.
How do they get away with it? Easy with a captive customer base. I'll be going to Edgbaston in a couple of weeks, but with cricket, it's normal to roll up with your picnic hamper for the day.
Maybe football fans would be better off taking their own grub and drinks in a backpack. But of course they wouldn't be allowed inside the ground with that. So rolling up with a picnic hamper would really get the authorities going bonkers.
