One time I had a guy try to tell me I could only use an ability with "Counter" on it once per turn. He didn't seem to fond of the idea I blew up his S3 Impact monster using Gratos, can't recall what, and was about to do the same to his Gemclone. He eventually believed me after a long discussion regarding the keyword and several links to rulings, ut he was still suspicious I think.
