No, you'll look a right wally.Tell B that you have a firm OFFER from another company who are now putting you under pressure to ACCEPT their offer and have given you a deadline of two more days.Explain to Firm B, that you of course, do not want to accept the offer from A, but as it is a firm written offer, you are worried about turning it down, when all you have is a verbal indication from B.Ask if B could possibly rush through the letter confirming their offer and thus set your mind at rest (and allow you not to take up A's offer). Failing that could you get an e-mail with the basics of the offer from the HR department?Gee - I hope you're more decisive on projects...
