"We wanted to do a promotion but we're not really sure we want any response"

SMRT, Singapore's dominant public transport and taxi operator, clearly hasn't figured out how to do SMS promotions.

This ad in SMRT's subway trains tells you how to participate by sending an SMS with your taxi's licence plate number, receipt number, journey start date & time, and your passport or identity card number. Seriously. The ad even gives an example how simple such an SMS would look: SMRT, SHB1234A, 999, 011105, 1033, S77712345A.

Let's just hope SMRT didn't deploy too many extra taxis to cope with promotional demand...
