A word to the wise: If you're so stoned you leave your stash in a public place, practice great care when attempting to retrieve it.

Great care was not used by one gentleman from Exeter City in the UK. The would-be drug dealer left his wares, aptly described as a "large bag of cannabis," on the counter of a local shop.

While the size of the bag was not mentioned, there was enough weed to prompt shop owners to call the authorities.

Police responded to the call just as the owner of the pot was popping in the shop to retrieve his herbage. The man is now in custody facing charges of intent to supply.

In a tweet Exeter City Police said: "Male leaves bag at till (containing large bag of cannabis) then returns to store to ask for it back! One in custody for intent to supply."
