Just thought of another one -
Same bar, couple weeks ago, all electric tripped behind the bar. No idea why, phoned sparky out on call out. Sunday PM, about 10pm. I could use the pumps but the glass washer, fridges, till etc were all off behind the bar as it was confined to a fault behind the bar.
I moved the till into the kitchen area beside the bar where I had electricity and also had to wash glasses in the sink in the kitchen/use the 'normal' dishwasher for glasses, meaning I wasn't behind the bar at all times, as I tried to get through the rest of my shift without causing a disruption.
Customer complained that I wasn't behind the bar 'all the time', the the bottles in the fridge were 'warm' (fridges had only been off less than 30 mins and hadn't been opened so were still icy cold inside, he wasn't even drinking the bottles out of the fridge!), that he couldn't see my till (don't know what he was implying, as everything is fully accounted for via stock-checking), and complained if I was washing glasses in the kitchen as the bar was left unattended! As you have to walk through the 'kitchen' area to get behind the bar, I'd be able to see anyone trying to get behind the bar. I pointed out that as I was 'in charge' as the only member of staff to be in, I could close the bar on the account of having no electricity until the electrician turned up, but as I was making the best of a bad situation and ensuring my customers had good service, and he didn't have to go home, he sharp shut up.
The same person complains about bar staff going to the toilet (he waits until we go to the loo then moans he's been waiting for a drink for x minutes, even if he had a full glass before we left), he complains if the music is too loud, bingo caller calls too loud/or he can't hear him. He's just a serial moaner.
