A Warm Inviting Public Bathroom, is That Too Much To Ask?

The lighting in most bathrooms is just awful. Why is this? I took this picture in a Starbucks bathroom. I notice that most public bathrooms have lighting that creates a dimly lit environment. This creates darker spaces with shadows galore. Also the light actually in the space never feels warm or inviting. It's kind of like they are creating a space that makes the customer feel like getting in an out of the bathroom quickly. Its not a place you want to be in for long. Now, I am not saying I want to hang out in a public bathroom haha, I am just wishing there were brighter, more warm bathroom spaces to be in while doing something so personal.
