I cannot be the only one who has made this experience. Over the last year or so I have been overcharged any number of times in corner shops. Sometimes for as little as 10p, at other for amounts of £1 or more. The thing is these shops have all Afghanistani or Pakistani employees. Now, it may be that some of these are not very numerate. In fact, that is often the case. But I have evidence that this happens in the least of cases.

Possibly they are poorly paid and wish to augment their wages in this way. On the other hand it could be that Muslim leaders have instructed their followers to overcharge the infidel and contribute this money to their causes in Afghanistan or Iraq? I firmly believe this is a distinct probability.
