How lovely! And doesn't it make a nice change to report good customer service?
Just an aside, these things stay in the mind for a long time. When I worked in a BMW dealership I had a customer come in to buy a brand new car, a young Black working class man who had done well . He told me why he preferred BM's.
When he was a kid growing up in a poor area of South London he was car-mad and always dreamed of owning a BMW one day. He used to visit dealerships regularly, just to drool over the cars. Our dealership was the only one who didn't tell him to sod off and not to breathe on their precious cars. Instead the staff welcomed him and chatted away to him, listening to his 8 or 9 year old hopes and dreams.
He never forgot and when he grew up he made our dealership the only one he'd do business with.
