Translated. I had a hell of a time with 都産貿内, but apparently it's short for 東京都立産業貿易センター (Tokyo Trade Center, or Tokyo Metropolitan Small Business Center), which is a building frequently used for doujinshi events (but not comiket... at least, not recently).
Whew!A request from Ryouko ♡Did you really follow the rules?Doesn't mean much coming from you...You over there, please refrain from doing that heavy breathing for so long.Please don't sit and read doujinshi for long periods of time.Also, please take your trash back with you.O..ok. (By trash, she's referring to the tissues, right?)I'm done!I followed the rules so I had a great time.Everybody, follow the rules, and have a great day today!Oh, are you, now...Please take your trash back with you. (Please don't throw it in the Tokyo Trade Center's trash cans)
