I've no issue with being searched but, in my experience, many people in security have seemed to be more concerned about people bringing in their own food and drink than more serious matters.

As far as booze is concerned, if there's a bar I can see the point and drugs should obviously be discouraged. However, I've often been refused permission to bring in bottles of water, sandwiches, snacks and so on.

Yes, there may be food stalls but they invariably don't meet the strict dietary requirements which many of us with health issues have to abide by. Also, it is important for many people to keep as well hydrated as possible and it's unfair to force us to purchase bottled water at inflated prices.

So, by all means, increase security but don't use it as an excuse to benefit festival traders.
