Yes, I do take fast food into another restaurant for my almost 4 year old who does not have food allergies. Why? Because she is the pickiest eater on the face of the earth. Always has been; I have video of her picking green beans out of her food and throwing them on the floor at 10 months old. She never ate baby food...I have dealt with this since she was able to eat. I wish she wasn't so picky. It worries me to death that she will eat no vegetables, no fruit. The only meat she will eat are Arby's roast beef sandwiches or a chic fil a sandwich.
On a typical day, for breakfast she eats DRY toast (has said "no bubber" since she could talk) and a carton of yogurt, as long as it has no fruit in it.
For lunch, it's mac n cheese (only kraft, nothing else).
For dinner, EVERY night, it's scrambled eggs. Always the same. Never changes. So for me to finally get something in her that is meat, even if it is fast food, I am dancing. When we go out to dinner, we pick up a sandwich and take it with us to the restaurant of choice.
For someone who has never had a picky child, please don't say "you would never..." because you don't know what you'd do in a situation you've, thankfully, never had to deal with.
And please don't say that I am just trying to pacify a child. I have tried being adamant that she eat what everyone else eats. On the third day of her eating NOTHING and her becoming listless, I gave in.
At least I am not abusing her by making her eat what she does not want. There are too many people who are scarred, emotionally, by their parents demanding that the child eat something they are repulsed by.
If my bringing in a bag of food for my child bothers you, then when you own your own restaurant, you can tell me to leave. Until then, I will bring in food for my child and watch her munch along happily, while the other kids in the restaurant yell and scream and make the other patrons, including me, miserable.
Oh, and by the way, if an establishment is concerned about losing money on a $4.99 child's meal, they are already in a world of trouble, financially.
PS>>> We always tip 20-30% regardless of if the service was good, bad or otherwise, even if we are dining with or without the children.
