“I’ve started drinking my coffee out of a clear mug, so people know where my tolerance level is at”

“I’ve started drinking my coffee out of a clear mug, so people know where my tolerance level is at” is a coffee saying that has been printed on many images. The implication is that if the speaker’s coffee mug is still full of coffee, then the speaker has no tolerance.

If you drink your coffee out of a clear mug, people will know where your tolerance level is at.
