Not everywhere, but they are at Five Guys. They take a cup, fill it with fries, then put it in a paper bag (the size that most places give you to hold an entire order for two people. Then they fill the bag with fries.
Ultrasounds for cats and dogs are fairly standard in the UK. I don't think they are strictly required, but they will do them if they are unsure about a pregnancy or if they suspect complications. Not really a big deal and they are covered by insurance if they are deemed necessary (though not usually for pregnancy).
Just checked on my vets website and a pregnancy ultrasound is £90 for cats, dogs and rabbits.
