So, do you believe all business should be compelled to serve “customers” wearing ski-masks, goalie masks, Halloween masks, and any other face coverings?

Nope, didn't say that. I was just pointing out that, in this instance, it's pretty unlikely that this woman intended to commit a crime, and that your rationale (that she may have pulled out a gun after paying) was just as possible after the cashier refused service as it would have been had the cashier accepted the money and turned on the pump.

The bottom line is, the cashier, shouldn't have to try to determine which mask wearers are threats and which are not. Allowing masked individuals on the premises, which renders the essential deterrent and protection of security cameras useless, is a danger to the employees and customers.

If an individual drives around town in what looks like a ninja costume that person should expect to be treated like a potential criminal.

Did you look at the video or photo? This person looks frightening.
