A woman went into a deli in Philadelphia a few weeks ago and said she wanted to buy beer, but she didn’t have any money. The owner said no, you can’t have free beer.
This apparently made her so angry that she grabbed a can of hairspray and a lighter and made an improvised flamethrower which she used to torch a bunch of items in the store while the owner ran away.
Fortunately the fire didn’t spread. Police are still trying to track down the woman.
