I have done it only a couple of times in the past and invariably for foreign visitors.
Since it has been far and in between I have never resented it.
But I sure like to advertise that I stepped in and helped out when others had been reluctant!
*******On a sad note, two very elderly but awesome ladies with a zest for life, passed away the same night in different parts of the city. Both had been inspiring mothers and will be missed!
