Ordinary Gweilo

Fumier has already mentioned this, but never mind (from The Guardian):

When a middle-aged man swore at airline staff after he was refused a drink on a flight from Manchester to Tenerife, he got a sunshine break he had not bargained for. The pilot diverted the charter plane and dumped the troublesome holidaymaker 300 miles from his destination on a barren volcanic island off the west coast of Africa.

Well, a barren volcanic island with "several luxury hotels and a golf course".  Moreover, The Guardian reports that he "was was not detained in a cell and was released to enjoy the island’s famed tranquillity for 36 hours" before leaving the island.  So, not much of a punishment, really. 

The remaining passengers arrived in Tenerife nearly four hours late, and it must have cost the airline a large amount of money to make this detour.  Was it really such a good idea?

Perhaps they were worried that he might have wanted to smoke.
