I’ve been in this lounge for a few hours, am about to leave. Seen a few hundred people belly up to the bar. It is an open bar for business class. Bartenders are whirling dervishes, working really hard. People asking stupid questions like “do you only have India wines” and “may I taste it please?” Not a single person tipping. No wonder the bartenders remember me. What’s the matter with people? One of the iron clad laws of nature is “always tip your bartender.”
