What is the man going to do this weekend?

W: Hey! What’s the rush?
M: The bank closes in half an hour and I need to cash a check.
W: I can lend you some money.
M: I need to cash a check because I am going on a trip this weekend. Actually, I want to buy some traveller’s checks.
W: Hmm. Can I help you in any way?
M: You can drive me to the bank if you want to . My car is out of gas.
W: Yeah. Glad to. Let’s go.
M: Wait just a minute. I have to get my checkbook out the desk.
