Very true.

Also take into account that the delay will only happen for
the very first mail between two persons.  After that, the
tuple is auto-whitelisted, so any further mails will get
through without delay.  If you enable "lazyaw", then only
the sender IP will be taken into account, so the delay
won't happen even for different recipients.

I think the root cause of the complaints from Dave's sales
department is the fact that they don't fully understand
how greylisting works.  Explain it to them, also explain
the auto-whitelist function.  Explain that certain clients
can be excluded from greylisting if they absolutely want
so.  Explain the benefits, create and show statistics of
spam delivery, estimates of saved bandwidth etc.  Don't
forget to mention that spam costs time, and time is
money.  Also, bandwidth costs money.  Thus greylisting
can save a considerable amount of money.
