I wonder and I dont know if I just have a bad perception about the word good luck but I often see people who seem in hurry in tradery say you good luck when they refuse a trade or you put yourself busy because you cannot at the moment and they wish to only trade right now and cancel and wish you good luck. Is it kind of condescending or I have just a wrong view about it and it's just plain good luck without any bad intend????
