In a new video, TikToker @Chadderrall warns that there are baristas out there “posting and boasting” about changing the orders of rude customers.

It seems like harmless revenge, but it could have dire consequences for all involved; the customer, the baristas, and the place of business.

After all, that customer could have an allergy or heart condition, and messing with their order could be deadly. Not only could the baristas be fired once this behavior is known but their employers could be liable for any danger they put customers in.

Bottom line: quit being rude to your baristas – and don’t mess with someone’s food.
