Design a chair that swallows &nd ejects the passenger if certain criteria is met ;
Overuse of perfume/aftershave - have a shower, dont douse youself in cheap smellies in the hope no-one will notice.Even Bluebottles will die gettibg close to you.
Bluetooth conversations- i don,t want sit next to someone who randomly spouts out words to thin air.
Disable social media - theres nothing like a group of people laughing like chimpanzees on crack watching a video of their mate, to make me want to throw myself under the bus i,m on.
Eating - no i don,t want to hear or smell your need to consume food because you cant survive that 15 minute jouney without stuffing your face.
ELBOWS - Aargh too much.............
