Guys, would you like it if a girl gave you her number without your asking for it?

There's a guy I really like. I'm not sure if he likes me or is just friendly. We talk a lot when I'm in the shop where he works and he always gives me little discounts on whatever I buy-not a lot, usually less than a dollar. My friends keep telling me I should give him my number, but I don't want to irritate him or make him uncomfortable.
So guys: would you like it if a girl gave you her number unsolicited? Or would it be too aggressive/forward?
How would you want a girl to go about it?
