I just can't wrap a handle on the excuse that the OP was spending way too long in the ladies room. Lets say she walked in at 8:00 AM and didn't plan on leaving until 5:00 PM that afternoon because she and her friends were playing poker. What difference does it make? The idiot could have let her son use the mens room where there was a lot of room. Or she could have stopped by either mens or womens room door and announce she had to take here xx year old son into the restroom. She choose to just walk him into the ladies room where there wasn't any room according to you, JJBIRISH and shock the occupants. I just don't get it....obviously you also just don't get it.
I wasn't there, so I don't know if the boy had to have his mother hold his hand or not, but he should not be in the ladies room unannounced.
