What kind of business is the speaker most likely calling?

Hello, my name is George Frost. I’d like to reserve one of the tennis courts for tomorrow afternoon. I’ll be having a game with three other guests. We’d like to start at around 2 P.M. but we have other things to do, so after that would be fine, too. We’re hoping to play for two hours if possible. I tried reserving the court online, but uh, the Web site seems to be having some problems. I thought I’d try calling you instead. I’ll be in a meeting all morning so if you could send me a text message at 555-8432, that would be great.
