Fuck queuing I'll only do it if it's absolutely necessary and never by choice. I have to do it at airports if I want to go abroad, to get into football and in a supermarket to buy food. Small queues are inevitable but I'm not waiting in a large slow moving one unless I have very little choice.
I can do quite a good impersonation of a tannoy by cupping my hands and shouting. A few times I've been stuck in a queue somewhere with about two slow moving till operators working and six other tills sitting unmanned. Meanwhile loads of staff are mooching about behind the scenes doing fuck all but pretending to be busy. Tk Max is a prime example of this. I cup my hands and shout, "All till operators to tills, all till operators to tills please!" It works 99% of the time, much to the amusement and delight of those near me in the queue. Whether they think it's a real announcement, or it shames a manager into actually doing something, I don't care. It gets more tills opened lol.
