We don't really like passengers eating hot food on the bus. It's greasy which can be easily transferred to the seats for other passengers to get on clothes or bits of this greasy food can end up on the floor for other passengers to slip on. It smells and lingers on the bus long after the food has been eaten and even if none of the food does end up on the seats, floor or other passengers clothes it leaves an unsightly mess as seen here.
So when you get on in Union Street Torquay and ask for a ticket to Brixham clutching a bag of fast food don't be surprised if I am a little sceptical when I doubt your assertion that you are not going to eat your KFC or Big Mac but sit there on the bus for 40 minutes while your food, which is just about edible when hot (provided that is you haven't eaten for two days) gets colder and colder. In which case the only residents of the Bay who are likely to want eat it have webbed feet and white feathers and a big yellow beak. Sorry, you bought the stuff in KFC or MacDonald's so eat it in KFC or MacDonalds or even the street but not on my bus thank you.
