Mother of the Year Award (NOT) take 2

Ryan received an invitation from his scout leaders, Sunday evening, inviting him to dress like a character in his favorite book for his pack meeting on Wednesday. Monday evening Ryan had decided that he wanted to dress like Harry Potter. So Tuesday after school we took a trip to deseret industries to see if we could find a black robe. Taylor informed us upon entering the store that he wanted to go look at the toys. Colby volunteered to go with him while Ryan and I looked for bathrobes. After a few minutes of looking I heard a muffled announcement over the intercom..." Attention all customers, " the rest of the message sounded like the 'teacher' on the peanuts cartoon. Ryan and I found a black, shiny robe that he was happy with...but it was missing the belt... so we went to another part of the store to look through the belts. On our way I told Ryan I was going to check on Colby and Taylor in the toy isle. They weren't there so I went to check for them in the book section. A couple of times while I was wandering around I hear the muffled message again, but I wasn't concerned about what the 'blue light special' was for the day. Colby and Taylor weren't in the book section either so I found Ryan and told him I was going to the front of the store to look for them. As I approached the checkout area I heard the message again. "Attention all customers, if you have lost your child please go to register 1". I still wasn't alarmed by the message because I was sure that Colby and Taylor were together and that they weren't lost....that was until, Colby came up behind me and said "Mom, I can't find Taylor."
So I very calmly made my way to register 1. When I approached the register there was a line of customers waiting to be helped. So I walked to the opposite end in hopes of catching her attention and avoiding the line. But the cashier was flustered and was ignoring my "excuse me ma'am" So I just stepped to the end of the line. As I was waiting in line I heard the announcement over the intercom again. Then things got really interesting.

Lady at register 5, calling to lady at register 1, "Isn't that sad?"
Lady at register 1, "Really sad."
Lady at 5, " Some parent doesn't even know they've lost their child"
Lady at 1, " That poor kid"
customer checking out at 5 " Yeah, Those parents that just let their kids run wild through the store."
At this point, I was the front of the line and as Lady at 1 made eye contact with me, she must have sensed that I wasn't there to pay for the black robe I was holding and the smile on her face dropped as I said " I heard the announcement about the lost child and I believe he is mine. "
Lady at 5, " Did you hear us?"
Me " yes"
Lady at 5, " I am so sorry ."
Me " You know this little incident has taught me a very valuable lesson. We really shouldn't judge people. You don't know me... and you don't know anything about the situation... You were just making assumptions about me and what kind of parent you THINK I am. That's whats sad."
She apologized again as she picked up her phone to call for someone to escort me into the 'employee's only" door and into an office to where Taylor sat.

We finished our shopping and proceeded to check out 2, which was now open, to pay for our items. As I was paying the lady from register 1 turns around and pats me on the shoulder and says"Don't beat yourself up about it" to which all I could think to say was " Oh, I won't". She looked kind of puzzled as she mumbled " Oh,...Good some people would" and turned to help the next customer.
I'm sure my picture is now hanging in the D.I. With the words "Bad Mother" posted beneath it.
