What annoys me is that most people wont ask if you don't mind before they light up. I just had potentially my best round ever ruined by a bunch of pot heads, I don't touch the stuff so getting what they call a contact high happens fairly easy, I played the front nine 1 under and was only 2 over by the 16th hole when on the tee at 15 three of them started blazing away and I tried to avoid getting in contact with that smoke but it was everywhere and of course no wind that day. By the time I reached 16 my head was swimming and proceeded to get a quadruple 8 thanks a lot, I was so pissed I finished 7 over on those last three holes, shooting a good score is no easy feat either at my course 73.5 rate 139 slope. Just want to let anyone out there that thinks it's okay to just blaze away cause your playing partner you just met is an easy going guy and wont say anything is a very rude and lame thing to do.
