This company is a disaster when it comes to organizing events. Yesterday we went to the Cabra Carnival festival. Upon entering, they wouldn't let you bring in any food or drinks, except for uncapped water, which I had no objection to. But imagine my surprise when I went to the bar during the break and they had absolutely nothing to eat—no sandwiches, no chips, they'd even run out of water. It was 11:30 PM, I'd been there since 9 PM and it lasted until 5 AM, and I still couldn't eat or drink anything. I asked if they could let me go outside to buy some sandwiches and come back, and they refused. They told me to eat them outside, which means I'd miss performances I'd paid to see.
In short, they're shameless. If they're preventing you from bringing anything in, they must not have enough supplies, especially since they didn't even have water in that heat. Then they tell you they're going to restock, and you have to wait in the middle of the performance to see if you can go. If they can't organize things, they should definitely do something else.
