Transaction Man

If you've ever been to a timeshare sales event, you know what a Transaction salesperson is.  The Transaction Salesperson knows (or thinks) he'll never see you again, so anything if fair game--play on your guilt, play on any weakness he's been trained to spot.  He knows this is a one time shot and that sales is a numbers game:  talk fast and furious to enough people, and you'll land your quota.
So, the transaction salesperson is a popular style in situations where there is a one-time event with virtually no chance of seeing the customer again, so anything goes.  Beware of Transaction Man.
Never put your sales team into a situation where they feel that getting the sale is all there is. 
This style can be a danger to a commission only sales team.  If one's living is solely determined by commission, if the only way a sales person can survive is to close the deal--then you may be inadvertently creating Transaction Man.  A sales person has to be able to make a living with a base salary; a sales person has to be able to pay for his gas and expenses with an allowance.  If not, he may turn into Transaction Man and hurt your company's reputation.
