Regardless of whether you're the beer-drinking crowd or the disgusting gang, the truth is that no one likes to go to a bar, restaurant or pub and be served in a dirty glass, right? But how do you find out if your stupidly cold and perfectly on-the-spot beer isn't put in a “baptized” glass? There is an easy, easy method!

According to Kate Bernot of The Takeout, to see if the glass was not well cleaned after the beer is served, notice if gas bubbles form on the inner surface of the container. Kind of like the cups you can see in the following image:

It happens ...

According to Kate, when a glass is not rinsed properly or not thoroughly washed and some soap or dirt remains unnoticed and is left behind, the beer gas bubbles stick to this stain, denouncing the problem. Remember that in the case of bars, pubs and similar establishments, this can happen easily, since, due to the low light or high customer turnover, the attendants do not always see the glasses properly or have time to dry them correctly. .

In addition, the same effect can be observed in cups that were stored or stacked for some time and eventually accumulated dust. Either way, it would be ideal if all glasses were properly cleaned and polished before they were served to customers - and now you can know whether or not this was done with yours. So, dear reader, did you already know this method?
