I was just wondering if anyone else has run in to this. It keeps happening to me too often to be coincidence.
I quite often meet friends for lunch. I, of course, bring along my children. The places we go are in a stretch of restaurants/shops that really cater to the crowd of people who are grabbing lunch on their lunch break from work. I'd say most of the restaurants for workweek lunch that is 95% of their crowd. (But they are kid friendly, Chevy's, Old spaghetti, etc.)
So I have been noticing that if I go for lunch with my kids and a female friend (most of whom are on their lunch break) service is INCREDIBLY slow compared to if I go without kids or with dh. Orders of Magnitude slow. Like today we went to Chevy's Fresh Mex. No appetizers, no drinks, no special requests, no send backs. We ordered quickly and the meal took 1:45. Ridiculous. Everything was so freaking slow. Took forEVER to get service, took forEVER to get food, a bill, her to take the money, to get change.
This keeps happening. Lunches at places that normally take ~40 minutes taking over 90.
I am starting to really feel that they look at me and decide that we are "leisurely ladies who lunch" and not in a rush and so neglect us. Which if you have ever tried to lunch with a 3 year old and a 4 month old in tow, you know that FAST is key because a good mood is only destined to last so long.
Anyone else?

But I've had a few times with a waiter/waitress I didn't know who totally ignored me. The last was at Applebees. I sat there for 15 minutes before I went looking for a manager because I'd not been waited on for a drink or anything. She waited tables around me and I could never grab her attention. The manager got her there a.s.a.p. But her tip suffered for it. Yet the ones who know me wait on me right away. They know their tip will be good and that I clean up after my son. I think perhaps many of them are used to small mom tips and large kid messes to clean. And maybe they just subconciously stall.
That way they know not to take too much time with your order and you don't have to track anyone down to get the bill. Then you can do things as quickly or as slowly as you want. 

We end up at Applebees often, so most of the wait staff there know that we tip well and are patient with us, bringing us lots of refills.
