So I went into a computer centre (I won't tell you which one for fear of reprisal).
I got harassed and in particular, by one very pushy salesman. I was just looking around - browsing - and he was trying to sell anything and everything to me (granted, this is his job). Anyway, he offered his business card in case I needed something. I said "no thanks - I work two minutes away - I'll just come and see you if the occasion should arise" and he insisted on giving his card to me so I finally took it.
On the way back, loads of hawkers were out and one company (known for its very aggressive marketing techniques) had the slogan "Give us your business card and we'll give you a free bag!". So I did - with his business card. I agreed that I could be contacted in every way about everything.
Mwahaha
I really hope he doesn't find out.
