My favourite had to be the dude who, upon reading the instructions on a packet of pasta n sauce, emptied all the ingredients into the hall's kettle and taped the button down so it continuously boiled for ten minutes.

Also a yah girl I used to do OTC with, who was most definitely one of these living out of daddy's wallet types, I met in Tesco one day filling her basket with sandwiches and cold chicken and crisps and... just things that you could eat straight out the packet. Upon questioning her strange shopping collection, it was discovered she doesn't cook. At all. Not even toast.

"So, do you not cook pasta or anything? That's really easy to do."
"But... don't you, like, have to, like, boil the water and stuff?"

Poor dear was missing her housekeepers.
