I WISH that this announcement was made on my CUN-RDU flight yesterday.... or at least put the curtain down to give people the idea that "maybe" they shouldn't use the lav there if the one in back is available. I was in 1C and in a 2.5 hours there had to be at least 30 people coming up and using the lav beside me... I was actually bumped more than once by people waiting in line for it.
I really dislike the MD88's.
