Years ago, a guy I worked with had his infant with him...he went into a Starbucks to see if they could warm up the baby bottle....they refused, citing some health department regs.
When my youngest was two she had to urinate.
We were in Rite Aid. I asked to permit her to use the bathroom. They refused, and she started crying and wet herself, the cart she was sitting on and all the items in the cart. I was so angry that I still wont go in their lousy stores.
