Looks like a great spread to me - I've seen far worse. So you expect the manager tasked with telling you to be in two places at once? He took the time to personally deliver the message, rather than stick it in the post, & you take out for a meal & that's wrong? I don't know what the "presecco" (or do you mean Prosecco?) quote means, NATS has a clear policy on alcohol in the workplace, there's none at Whiteley or Southampton if you prefer.
You also missed one: someone got a posting 1300 miles from their training base, but they're not whinging - would you prefer that? Your "adjustment time" was when you signed the contract. What happened to...
"NATS will send you wherever they want. You will have no personal control of your destiny. NATS decide if you are going to be selected for Aerodrome or Area ( probably at a toss of a coin! ), and their commercial necessity will determine your posting.
It’s all part of the fun"
