While I won't argue with the underlying point Steve's logic with respect 
to the addition of an AND clause to the sentence, I will pit nits and 
throw another view point into the mix.

Firstly, logically speaking, isn't there a difference between:
- If A, and then B
and
- If A and B

The first implies a wait or sequence between events A and B. It does not 
imply that the events are simultaneous nor that they need to be 
maintained. If A happens, stops, then six months later B happens, the 
first statement is true. The second statement is true only while both 
events are happening (and they could start in any order).

Secondly, Why does the sentence even contain "then" in the first place? 
(You don't even include THEN in If statements in many languages.)

>From the original post: If <blah, blah>, then <blah, blah>.

Why not: If <blah, blah>, <blah, blah>.

Thirdly, as far as using "because we've always done it this way." as a 
reason, there is absolutely nothing wrong with that. The burden of proof 
is on the person suggesting a change. They must prove that their proposed 
change has demonstrable advantages over the old way. If they can prove 
benefit, only then is the old guard's complaint of "we've always done it 
this way." become irrelevant.

It doesn't make you popular, but a simple "Choosing between two 
unsubstantiated choices, we'll stick with the way it's done." or "I 
understand you like it better that way, but we've already made a choice." 
are valid arguments against change.
