Very strange experience here.. The billboard out front advertised cold drinks, amongst other things. I went in the classroom half accidentally and the girl working there was quite friendly and directed me through to the store half. The girl working in the store ignored me while talking on the phone and then rudely told me they had nothing to sell because they weren't open.
Obviously, I have no problem if the store is not open yet, but maybe don't put your billboard out front, direct me around the store, ignore me, and then rudely tell me to leave.
