Did u yoos seil chequer on yer tag lyin?
Next question is, if he fixes the typo in his next post, does it change it in all prior posts? I.e. is the tagline stored separately for each post, or (more likely) in one place in a database from which all posts are tagged?
I guess we'll find out...

Ah geez. Major retail stores have been doing this forever. When I worked for dept store part time in the 70’s; they checked us as left work. They have that policy in place because of theft. The stores don’t want you taking their stuff free of charge. A lot of in store thefts are inside jobs. What’s wrong with looking in your bags. I am sure the employees know this. Sounds like more political propaganda BS. Look at Walmart? They check customers as well as employees.
