Brain Teaser...I need the extra credit

[lotus776]

My teacher periodically gives us these math teasers that are kinda fun to reason through so I post them on 2+2 to give you guys something other than poker to talk about.
Here we go:

Clark, Jones, Morgan, and Smith are four men whose occupations are butcher, druggist, grocer, and policeman, though not necessarily in that order.
a) Clark and Jones are neighbors who take turns driving each other to work.
b) Jones makes more money than Morgan does.
c) Clark beats Smith regularly at bownling.
d) The butcher always walks to work.
e) he policeman doesn't live near the druggist
f) the only time the grocer and the policeman ever met was when the policeman arrested the grocer for speeding.
g) the policeman makes more money than the druggist or grocer.

what is each man's occupation?
