Security people are not always fun police out to ruin a good time.
They are hired to ensure the majority of people enjoy themselves, and to follow a set of rules. It can go wrong, though, when the rules are a little silly.
There is little scope for a security guard to exercise discretion, they have not set the rules - they are contractually obliged to enforce them.
As Northlander Tony Edwards found out, the rules can be a bit silly sometimes.
The flag he has carted to cricket matches featuring England for 15 years was ripped off its broom handle before the final Black Caps and England one-dayer on Saturday.
