You're on holiday, minding your own business, when a guy or gal ambushes you on the street and by some means , manages to get you into a taxi to go and suffer a Timeshare presentation at a (hopefully) nearby resort, in return for some gift. These people work for the Timeshare Companies and are known as OPCs because they approcah people off the premises, and provide the resorts with a steady stream of people to sell Timeshare to.
