Simple typo. Happens all the time.
I had to be very careful when I worked in “pubLic” works department.
When I was working, we had a lot of retirees from our closed plant in Gary, Indiana. Due to arthritis in my hands, whenever I typed out a retirement application, I was always typing “Garky”. I fixed that by having the auto correct function in Word change it to “Gary”......
Ooooooh yeah! That’s one you have to be very careful with. LOL
True story.
In 1982 when I hung out my shingle on the main street of town as a CPA, I had a big beautiful sign hand painted to announce my location.
The ornate sign was about 2 ft high and 3 ft wide, hanging from a sign post so it was visible from both directions.
Problem was, on both sides of the sign, in letters several inches high, directly under my name, were the words CERTIFIED PUBIC ACCOUNTANT.
I took pictures of the sign before I returned it for correction.
