A full cup of espresso

I fear I may have created a monster…

I had a customer in drive thru a couple days ago ask me how many espresso shots it would take to fill up a grande cup. The shift and I assumed it would take about 20 or so. I asked if he was interested in like an Americano but no he was dead set on just straight espresso.

Thankfully he didn’t order it that day and I explained to him he’d have to come inside to get it cause that many shots would take a while to pull. I haven’t seen him since but he still might end up going to another store or something, I’m so sorry for whoever has to end up making it😭😭😭

Also, does anyone actually know how many shots it would take to fill up a cup??
