With the upcoming ban on flasks, we find this unacceptable for many people. Some people bring soup to a game (something that is not sold at the stadium), some people bring tea or coffee as they cannot afford to buy Hot Drinks at the stadium. (This may be a family or someone on a reduced income).
A flask at football is a right of passage and is for refreshment purposes not as a weapon.
How many times has a football player been hit with a rogue flask?
Is this really for safety or a way of increasing revenue from drink sales?
