Had the tour on loose cannon and then stopped for a drink, was informed that each person who was on the tour was entitled to a free drink, however the staff disregarded us for about 30mins,then told us it was a special type of drink which had to be made, drink was made but everyone who waited didn't get a drink as enough wasn't made available for everyone, the drink tasted like piss and they were left on the counter, customer service is of essence when doing business
