Salesman do stop us along our way to promote their products. However, not all that they sell are what we need.
But then again, I find it uncomfortable to just snub them if we know that we don't need that items. Afterall, it's their job. Their livelihood.
I have been approached, on a number of occasions, by cable television salesmen selling their products - particularly the English Premier League paid-to-air tv channel. I have been trying a few techniques to manage this, and I think this works best for me:
Salesman (of a paid sports channel): Hey, bro! Do you watch soccer? EPL?
Me: Yes, of course. Love soccer!
Salesman: Cool. Have u got your cable TV for sports channel to catch EPL?
Me: Unfortunately, no. I havent subscribed yet...
Salesman: <sounds excited> Really? Let me share some of the plans for EPL...
Me: It's ok... Not now... My club is not in in EPL tis season...
Salesman: oh!? Which club?
Me: Nottingham Forest. Heard of it?
Salesman: Err... Kinda familiar...
Me: I'll subscribe when Forest is back... Next season, i hope. Have a good day!
