That's why in the real world you fake fire the next guy going to lunch, so his reward for being yelled at a bit and fired was an extra long lunch hour.
Also when I worked retail back when high school kids held the minimum wage jobs, annual retail turnover often exceeded 100%, so if lady waffles is having multiple problems in a couple months, your store has a problem far beyond angry waffles.
The American version at the store I worked at both as a labor drone and eventually as a night shift manager while in school, was to send coworkers to the office to be yelled at. The store was urban and near the bar district so at night, customers were generally drunk and guilty until proven innocent. Drunk people usually don't want to draw attention to themselves, mostly, so we had few complaints.
Its a mid to high skilled workplace thing to assume employees are yelled at. For manual labor work, the cost of replacement, either of the job or the employee, is very low, and most firing offenses had legal involvement (stealing cash or product from the store, for example) so discipline never went much beyond asking someone "WTF?".
