41.The following appeared in a memo from the vice president of a
food-distribution company with food-storage warehouses in several cities.

"Recently we signed a contract with The Fly-Away Pest-Control Company to
provide pest-control services at our fast-food warehouse in Palm City, but
last month we discovered that over $20,000 worth of food there had been
destroyed by pest damage. Meanwhile, the Buzzoff Pest-Control Company,
which we have used for many years, continued to service our warehouse in
Wintervale, and last month only $10,000 worth of the food stored there had
been destroyed by pest damage. Even though the price charged by Fly-Away
is considerably lower, our best means of saving money is to return to
Buzzoff Company for all our pest-control services."

最近我们和Fly-Away Pest-Control公司签订了一项合同来为我们在Palm
City的快餐食品仓库提供杀虫服务，但上个月我们发现，那里有价值超过$20000的食品被害虫破坏。同时，我们使用多年的Buzzoff
Pest-Control公司继续在Wintervale的仓库服务，上个月那里只有价值$10000的食品被害虫破坏。尽管Fly-Away的收费低廉的多，我们节省收费的最好方式就是重新使用Buzzoff公司来提供我们所有的杀虫服务。

1.P和W城市环境不同，有可能P的环境非常差，所以损失$20000其实是比较正常的，如果P地采用B的服务，有可能损失的会更多。

2.没有给出两个地区保管食品的总量，有可能P城市保管的食品很多，$20000只是很少的一部分，这样说来采用F的服务是很划算的。

3.没有给出两个公司的具体费用，有可能具体的费用加上被破坏的食品的价值，F公司的服务还是比较优惠，所以不能够得出重新使用B的服务的结论。

4.除了这两个公司之外，有没有更好的选择。可能有其他的公司能提供更好的服务，且费用也更低。那么B就不是最好的选择了。
