Was I being rude to the waiter?

So I went to this upscale French restaurant a while back. The food, atmosphere, and service was great. Our waiter chatted with us for a bit, Ben, if I remember his name. The bill came to $240, I only had 100s, so I left $300, and I guess I could've left it all as a tip, but for some reason, I asked for $10 back. We got a cold shoulder from the waiter from that point on. In hindsight, I should've just left $60 as a tip, but it seemed like a large tip, was I being that rude?
