There were a few couples in my cong that did similar for the chance to be career witnesses. Two of the couples are back in town now dejected crying the "end of an era" the other are still in Equador last I heard on their own ticket looking for english speaking people to witness to - how ironic.
On a side note I ran into one of the couples in town one day and they told me all about their experience and why they were back.
After reading about closures and lay offs I decided to throw this question out there
"so what about the branch (the branch where they were) will they sell it?" and the husband who had been letting the wife do the talking up until this point immediately spoke up and said
"of course they will they're not sentimental"
I then said
"well they are not sentimental about their own people why would they be sentimental about some buildings."
He said "true , true."
I went away thinking hmmm interesting.
