This fuel station installed cheeky size labels on men's urinals in Thailand.

The PTT gas station in Yasothon province put an amusing spin on the public restroom by affixing size labels - ranging from SS to XXL - on the urinals for men to use based on the size of their member.

While some customers may have hastily picked their urinals without much thought, others gamely joined in on the tongue-in-cheek fun by going straight for the urinal with the XXL label.

Anchalee Pitchart, the station's manager, was quick to clear the air about the humorous labels.

She said that these were placed solely for entertainment, 'aesthetics and orderliness', and that men of any penis size were welcome to use the urinals.
