Some silly thoughts about pokemon centers in the settings:

Under the careful watch of the Joysdottar foundation and funded with generous grants from you know who, pokemon centers are a model of efficiency. Director Joy Joysdottar has streamlined the pokemon healing process and associated trainer services attempting to both decrease serious medical incidents through the 'whole team care' initiative and to decrease healing time to make the centers less of a target for the ne'er-do-wells that have plagued less industrious regions.

In lieu of TM shops or local goods, pokemon centers will often have medical equipment to look after the trainers themselves. After all, who else would you trust your blood samples and medical history to? In addition, each center is stocked with not just battle essentials but traveling requisites like backpacks, trail bars, and towels.

These centers do not commonly focus of hospitality, but still provide meal service for traveling trainers. Nutritious and hearty meals are served, just like mom used to make (but 'love' is not a recognized ingredient so is left out). In some places, it has become custom for present trainers to share any flavor enhancers like cinnamon or hot sauce with all present. A trainer with an eye for berries soon becomes everyone's fast friend.

And don't worry, if worst comes to worse, the state-of-the-art Rotom systems take security VERY SERIOUSLY
