My friend, Stephie, posed the question “[What is] the trend of tipping at the counter (example – Starbucks).”

And I replied to Stephie with this fun tale:

My ex-sister in law who worked at Flying Star not only wanted to be tipped at the counter, she also expected to find a gratuity on the table.

Her logic: “It’s hard for me to make a living with any less than 30% tips.”
My logic: “You’re crashing on our couch, not paying rent or utilities. Take your 30% tips and find your own place. You have one week.”

I don’t know if this answers your query. I simply enjoy impugning my ex-sister in law’s constitution and I love this story.
