W: You can bring up to 3 at any one time.
M: Hum. That’s good.

M: How much do the lockers cost?
W: Forty cents. But you get the coin back when you take your things out. Right, and the tennis courts are round here to the left.
M: Hum. And we can play for an hour at a time?
W: You can take the courts for thirty minutes or an hour. But you can carry on playing until the next player arrives.
M: Of course. What about care or bar?
W: Yes, we have a club room which serves drink and food behind the reception. The club room is open until 11 o’clock. But all players must leave the courts by 10 o’clock.
