much as the world hates telemarketers, i have taken a fancy to them. especially here in chennai. for one, they are quite courteous and come with no urge to push the product into your hands. their intentions are purely entertainment in nature. your entertainment.
XYZ Bank: "Sir, calling from XYZ Credit Card division..."
me: "Uh.. no thank you"
XYZ Bank: "Ok" *click*
the call lasts all of 8 seconds, solely based on your ability to prolong it. (next time i shall follow that "uh.." with a "hmmm...") but leaves you with a very good feeling at the end of it. you dont have to shout/abuse the caller at the other end, quite politely (and gladly) he/she agrees to put the phone down (in most cases beats you to it) and also gives you that much appreciated power break in the midst of work :)
