every retail worker should be allowed to murder one (1) customer during holiday season. i've been saying this for years. it works because its not an excessive amount of murder, but customers wont know which retail worker has already used up their annual murder.
the customers dont know which retail worker has used up their murder so they are likelier to be on their best behaviour. https://twitter.com/IxnayCrabwinkle/status/1335658415805390855
if a customer is still an asshole despite this, they will likely be an asshole to more employees and the retail worker can rest easy knowing one of their peers will murder them.
the thing is, it's a perfect system.
