There is no excuse if the sales people work for the same company, but do keep in mind that it'll be some companies themselves that insist on hard selling to their customers.

I once worked in one London store were you were reprimanded if you didn't approach a customer and ask 'how you could help them'. It wasn't too bad for me as I was working in gentleman's pyjamas (not literally) on the ground floor. By the time the customer had visited all five floors most would be in a furious rage after being asked the same thing twenty times.
