I have become the bitchy mom

Today wasn't the first experience, but I became the bithcy mom. I was in Toys R Us, (which I hate! with child or without). You always have to wait in a long line and it takes forever to get out of there. In addition (no offense to anyone) but the store associates could care less about their job and offer no help or insight. This is usually because not many people are working in the store. I finally reached a limit today after a bad beginning to my weekend, and snapped at the manager. I tried to buy a new baby gate with my daughter in her stroller. No help in getting it up to the register and then the long line. Everyone was annoyed and complaining because they had kids begging for more toys or on the brink of a tantrum from boredom and waiting. I finally asked to speak with the manager, and got the assistant manager. Before I finish, I was in retail for 10 years and managed stores, so you will hear no sympathy from me. I explained how miserable the experience is in this store any how annoyed the customers felt. I continued to say how much I resented even shopping in the store due to the lack of customer service. I tell you that if a new chain toy store came in with amazing customer service as their trademark, then parents would practically run to them.
While I on my rant, I cannot stand the American public in a retail store while your pushing your toddler in the cart. No one moves when you ask three times, and they act like it is such an inconvenience for them. It is that or when my daughter is talking up a storm while shopping, I get an annoying look. I have now reached my limit and have became "that woman" now. I now push my way through with a nasty excuse me or I like to make the comment, sorry to inconvenience you if they are really nasty. Seriously?! I mean it is not just mom's it is everyone. People are just plain rude. I swear when a man opens the door for me I almost fall over. What has happened to everyone? When I am out without my daughter, I am opening doors for mom's, helping them pick up toys and smiling and entertaining children while they are getting upset waiting in lines. My fellow mothers can understand me when I say it is difficult enough to run errands with a toddler, and to deal with rudeness and ignorance on top of it is just pushing the mommy bitch button.
