I would suspect that the only businesses in Calis that operate on a genuine 50% GP are those of the itinerant Sunglasses an Fake Perfume sellers. And at that, on a very low turnover.
I entirely agree with Keith that when idiot Brits put £20,000 or more into a bar that is gone within a year, things are seriously wrong. And in some cases competition is so fierce that people aren't making any money. Well, in some cases that is.
It does seem to me to be that there are certainly no fewer Bars on Calis prom and main street area than there were some 5 or 6 years ago, and there has not been a great increase in the number of visitors. There has been a significant increase in the number of bars in the nether regions for example Baris Manco Bulvari and the Sunday Market area, and these newish business all seem to be prospering nicely. Probably due to good management practises.
Maybe the number of Bars in the Calis area now exceeds saturation point, and some of those on the prom and Calis centre area are not effectively managed, so go broke.
As I have said before - relating to prices - and not neccessarily just of Efes:D
When faced with equally convenient Petrol Stations in the UK, do you deliberately go to the one that charges the most per litre, so as to prevent the alternative from going out of business due to being " undercut ". ?
I just might use a filling station in the UK which has dearer prices if I got a better service, say the sort of service you get here in Turkey where all the garages give attended service and offer a free car wash whenever you have a £10 or £20 fill up:
But in the light of the fact that this does not happen in the UK, I simply go for the cheapest price.
But in Bars here in Calis not all standards of service and "ambience" are the same. Which may, as well as in cases of poor management, account for why some Bars, charging almost identical prices for drinks and food, and in very similar locations, go out of business quite quickly.
