From Neurotic_Marauder, Tales From Retail:
This happened a few days ago. The names of those involved have been changed to protect the innocent.
I was on register duty at the clothing store I work at.
A customer came up with an insulated jacket. Her head was down, so I couldn't really see her face. She was searching something on her phone.
"I'm just checking to see if the coat is down, I'm allergic."
I shrugged and scanned the coat and removed the security tag.
As I was putting the coat into a plastic bag, the customer let out a small gleeful squeal and did a little jump.
"I'm just so excited! I love this coat!"
Again, I thought her behavior was a little odd... but strangely familiar.
I moved on to asking the customer for her e-mail to see if she was in the store's system.
As I typed in her last name, the gears began to slowly turn inside my head.
I haven't heard that name in years... the only person I knew who ever had that name was-
I looked up, and for the first time in 17 years I was looking at the face of my 4th grade teacher, Mrs. Jacobson.
I didn't know what to say, I actually covered my mouth and muttered "oh my god" several times before finally saying:
"You're Mrs. Jacobson"
It was then that I realized that I was about 2 feet taller than I was the last time I saw her, and I now had a full beard and glasses. There's no way she could possibly recognize me.
"I don't know if you remember me, but you were my 4th grade-"
Her eyes immediately widened and darted to my name tag.
She immediately wrapped me in a hug as I was still trying to comprehend what was happening.
We briefly caught up with each other - she told me about the family she has now, I told her about what I did after high school and college, etc.
Finally, after promising to add her on Facebook, she left and I was left with my dumbfounded co-workers staring at me.
My manager immediately came on the radio and asked:
"My wife is never that happy to see me, who was that?"
Despite someone stealing shoes later that day and an older customer complaining to me about shirt prices for several minutes, I couldn't shake that smile I had after seeing Mrs. Jacobson again.
tl;dr I reunited with my 4th grade teacher after 17 years while working the register at my store
