Pls this question has be bothering me since i started working in a hotel last week.. I discovered that beer drinkers do refill their cups when the one inside hasn't finish?? Is there any secret behind it?

Bro; this ur question funny, walahi!!! NL; d homee of commedians; well anyway; lemme give u my answer.m.

Because; when dey re drinking beer; it gets connected to their sperm pool; so if they allow, d beer finish in their cup, their spermm automatically dries up, n may leave them infertile; so they havve to be refilling until; the bottle is emmpty; so der don't suffer dat ill-fate; - hope dat helps

I do not know. But lemme try, they do it to bring out the full brew.

Dat is wat makes beer different from water
