A few years ago we met up with a British girl who worked as a tour guide on the boat trips around Crete. She came into the bar around 9pm sat next to us and chatted, she seemed ok, about 15 minutes later she fell to the ground and started fitting - I jumped off my bar stool and started moving the furniture out of the way thinking she had epilepsy, the owner of the bar phoned for an ambulance who came quickly and whisked her off to hospital- the bar owner was very apologetic as it was the first time we had visited the bar. We called back in the following day and asked after her - she was still in hospital, the diagnosis was that prior to going in that bar her drink had been spiked elsewhere - her partner was in the bar and she said that she had no history of the illness and it was all down to the "bomba" she had had slipped into her drink. Scary stuff - I'm always a bit wary of the "trendy" bars with their special offers as I'm bad enough on the good quality spirits!!
On the subject of Greeks and whiskey - also on Crete we used to visit a bar on the main road in Malia where the owner only drank either Guiness (daytime) or Jameson Whiskey (evenings) though this could have had something to do with his missus being Irish!!
