I saw the same thing at Best Buy. They switched from a traditional cash register to a web application on a PC. And all the clerks carefully (and slowly) navigated their mice to click on everything.
What was worse was their mouse platform wasn't level. So every time they let go, it would drift downwards and they'd have to go through the "where's my mouse pointer" wiggle again.
