Don't try to sell something to someone who doesn't want it or need it. Tell the truth, even if it costs you a sale. Always leave the customer with the best impression you can make (and a business card - it's surprising how customers change their mind in an emergency).
Great advice - mind if I 'steal' it?
That's not proprietary information, it's common sense! Please use at will and I wish you all the success you can handle (and maybe a little more - it's great to be in sales and have too many clients seeking you out)!
I can explain it to you but I can't understand it for you.
