For one day, dogs staffed a special bar in London. The well-trained dogs had small barrels on their collars. People put bottles inside the barrels and the dogs came to the customers. They would take the beer out of the barrel and enjoy it!
If you know about this bar, you could make a reservation and drink for free.
Difficult words: staff verb (to be the staff – to work somewhere), barrel (a wooden container or a box for a drink), collar (a band around an animal’s neck).
