As Bar Manager, you have just been advised by one of the bar attendants that a regular customer in the public bar has just complained about the air conditioning not being cold enough. It's a hot day, 40C outside, and the air conditioning is set at its usual 21C throughout the property. You do not have any ability to alter this setting. The bar is full of regular customers and a few new faces, and this is the first you have heard of any complaints. You go over to the customer, who is someone you know and notice they are sitting near a window which is closed: the window is tinted a bit, but it's still getting the full afternoon sun. And you notice the customer is sitting the furthest way possible from any of the air conditioning outlets in the bar - having a jacket on too probably doesn't help!
