What do you mean? What's wrong with going to a grand opening of Taco Bell. I went to one before and same thing happened. The whole town came to investigate and order food. It was fun and exciting and yes we waited for over an hour for food because Taco bell isn't meant for a massive flood of customers.
It was fun watching the workers stress out. haha. You said Ireland was boring a long time ago so going to a grand opening was probably something fun to do.
I've been to many and not because I'm hungry, but because I want to be part of the chaos, I've learned over the years to eat before you go because if you go on an empty stomach, you'll get upset. So I always eat before I go.
