Bath & Body Works Direct

Basically brought my girlfriend there to do some shopping upon waiting on her I needed to use the restroom an was told there's no public restroom so I ended going across the street in the rain an cold to urinate... which I think I very unfair so I wonder if it was an elder that need to go to the restroom I assume they would need to go across the street as well or be told there's no public rest room I also don't recall an sign saying there's no public restroom so If possible can someone explain to me or send the policy for a costumer or elder that needs to use the restroom.
