A gross example of these comprehension misses would be your reply "The membership fee has been reported as SEVEN dollars per year."
The reference was to the $500 berthing fee:
"...the Sea Scouts in 1998 were suddenly hit with a charge of more than $500 per month. No other nonprofit is required to pay to berth at the marina. The fee is imposed explicitly because of the Sea Scouts' affiliation with the Boy Scouts.
