Successive Timeouts

[kevin]

I was working a B-Team game the other night and the visiting team was getting waxed. The coach asked for a timeout which I gave him. After the first horn he asks for another timeout which I gave him. As I was waiting for the 2nd timeout to end I was hoping he didn't ask for a 3rd in a row because I wasn't sure on the ruling. Can a coach ask for all his/her timeouts in a row? I would appreciate some help. Thanks in advance.
