Pet sitters for your animals

I have no need for anyone to babysit my fish. They can go 2~3 weeks without food.

We do have a few professional pet sitters in the area. There is one doctor in the area who has to go out of town pretty much every week. He is a regular customer of one of those pet sitters because of his dog. Then one day, the pet sitter asked him if he would like a "free" dog. He said no. I thought it's funny. You can notice the intention of that offer right away. So instead of paying for one dog, he would have to pay for two dogs if he took on that "free" offer.
