About a restroom

Today I’m going to write about restrooms. 
Lately I have been surprised by restrooms in public places, especially in the service area of expressways. Surprisingly their restrooms are well-equipped and kept clean and tidy. They even installed a Washlet! I have had a rather bad image of expressway’s restrooms for some reason, but they have been improving steadily. I have no idea which government office is responsible for trying to improve public facilities and I generally don’t assess any of their actions, however, I really value their improving restrooms. Likewise, many department stores have made their restrooms better. We prefer to go shopping to such stores, don’t we? 
There is a good restaurant in Yamanashi prefecture. It’s my favorite one, but their restrooms are very small and I can’t feel positive that they will try to give their customers a comfortable place. They serve good food but I will not be going there soon. 
Thus a restroom is very important for their business.
