I can? Thank you.

On Wolverhampton station there is a facility where, if you have dog, you can fill a dog bowl with water so that your pet doesn't go thirsty. That's fine. What confuses me is the sign above it which reads

This facility is for the

use of our four-legged

friends.

Please quench your thirst

with our best wishes.

Even in Wolverhampton most of the dogs are unable to read so what I want to know is this... who exactly does the "your" in the second sentence refer to?
