Simple mistake

[Baz]

Last weekend a highly renowned CCR instructor was bemoaning his newly
returned Inspo head from APD. The air was blue with expletives about
rotten service etc. This was of course said instructor had just bailed
from a lesson with several wide eyed and ever keen students.
Complaints of massive CO2 hit and high praise for APD's service
department rang loudly around the Spit.

Said instructor and keen students inspected the said faulty
workmanship and several draft versions of the letter of complaint to
APD were verbally drafted.

Shame he failed to fit the space ring in the scrubber. ... Bloody
careless of APD to let him do that !
