Three well behaved dogs in a meeting

I had a meeting with two other blind women in a coffee shop yesterday.  Each of us has a guide dog.  Two black labs and one yellow lab.  We were looking at various braille displays and helping each other with technology.  I first want to publicly thank the coffee shop staff who carried hot beverages, moved one chair so there was more room for dogs, put two tables together for us, and generally were great and respectful.  Then, there were the dogs.  They all wagged a little at sight of each other.  But, then they all lay down and relaxed and caused no disturbances.  When we left the shop, they all guided to the door and when we all set off after, they worked like pros.
