According to the woman, why has the company gone over its budget this quarter?

M: We seem to have already gone over our budget on travel expenses this quarter. Do you know the reason?
W: Well, the main reason is because the airline we deal with has raised their fares.(62)On top of that, we had to change the hotel we use because many of our staff complained about being robbed during their trips. So, we signed a contract with another chain, and they are a bit more expensive.(62)
M: Well, we are going to have to do something to tighten up around here. Tell you what; from now on I want you to make sure you allow only those staff members who must take trips to go on them.(63)This way, we should be able to keep down the cost a bit. W: Actually, we have been doing that, but it’s hard to judge which trips should be allowed or not because everyone seems to have legitimate reasons for taking the trips.(64)I think we need to find other ways to cut costs. I’m meeting with the other managers today. Why don’t I bring up the issue at the meeting?
