I’ve seen some esophageal varices as a medic and let me tell you those guys are bleeders. Feel bad for people not knowing the situation, it honestly would look like he had something contagious so I can understand the freaking out. People barely survive this with care immediately available in a hospital so he really had no hope once it ruptured.
Fuck no, they’re paid to prepare food. There’s no service, why am I tipping? People who tip like this are the reason why we have a terrible time ordering every time we go out.
