Customer service is appreciated whenever it occurs. 

My wife and I (and I dare not forget Bandit) are spending a few days in 
Tucson, AZ at the Lazydays RV  Park. 
Gathered with us are close to 100 other Airstream rigs, from trailers, 
to motorhomes ... from new to vintage as is ours. 
The amenities are outstanding and, as usual, it is the people that make 
an experience memorable. 
They go out of their way to be friendly and accommodating. Their brochure 
says that all their employees take weekly service instruction. 

Can you identify a law firm that has done that?
