Refuses To Go Through The 20 cm Questions

(I bought a bed at Ikea and at the center it needed a piece of wood to sustain the weight. Just my luck, the part that came from IKEA was 10 cm too short. So I go to one of those large home-improvement stores where they sell everything you might need and will even cut the wood in the size you require, for free. I show the part to the employee and explain:)

Me: “I need a piece of wood just like this, but with 20 cm instead of 10 cm.”

Employee: “Sorry, we can’t. Our machine only cuts a minimum of 23 cm.”

Me: “You’re telling me there is no way you can cut a piece of wood exactly 20 cm?”

Employee: “That’s right.”

(I am a bit confused and walk around the store for a bit. At some point I pick up a 260 cm piece of wood and take it to the cutting area.)

Me: “Can you cut this exactly 240cm ?”

Employee: “Sure, give a few minutes.”

(He did and when he got back I had my 20 cm piece of wood to finish assembling the bed.)
