Oh my goodness, something similar happened to me!So I ring the hotel reception on they phone at the spa reception which says "main reception on the button" and explain calmly and totally in control of my emotions NOT, that they have locked me in their blinkin spa and have flipping well gone home thank you very much, so would someone like to come and let me out now pleeeeeease before I really spit my dummy out - arrrrrgh!!!! Can laugh about it now, could not at the time.
I'd taken my 4 month old daughter for some vaccinations and she'd gotten hungry. The nurse said I could use one of the rooms in the surgery to feed her. So she let me in, closed the door over and left me to it. When I came out, the place was in darkness The reception was empty, the corridors were empty, everywhere I looked! Turns out they'd all gone to staff training and forgotten about me :o As you say, can laugh about it now, but was scary at the time! :lol:
