TAB {no, not that kind} UPDATE
It had been settled, an investigation concluded yesterday.
As it was LUNCHTIME, I stayed for two pints and a catfish po-boy (blackened, with tasty remoulade and the most remarkable side of tangy crisps).
Delicious.
The payment system still confused, again with credit card, but just different to what one is used to, is all.
The free jukebox allowed me to confirm my favourite version of ‘Summertime’ is the Sarah Vaughan, so something good has emerged from the whole sorry episode (and not forgetting the po-boy, almost N’awlins-like in quality).
