Not suprised! My eldest worked as a bar manager in various places, the stories he told me about wine prices and part bottles being re-filled and corked to be sold again!, and this was at an AA Silver Star 4 Star rated hotel & Spa in Durham!..
He’s currently working at a Van Der Valk Hotel in Amsterdam, looks very nice but a meal for 2 in the restaurant is about €100-€175 so I won’e be going there any time soon!.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
