I’m a great believer in the cliche that there’s no such thing as a free lunch. Except, of course, if you’re in Las Vegas and take advantage of the vast array of bonuses and complimentary offers (‘comps’) on offer. It doesn’t take a psychologist to tell you that the psychology behind ‘comping’ is to get the gambler to spend more money. Comping is a legitimate psychological marketing strategy used as an incentive to get punters to gamble in the first place, or an incentive used to prolong gambling.

Here in the UK, we’re obviously not on the same level as Atlantic City or Las Vegas, but most gambling establishments offer an array of temptations to get you to gamble.
