Frank is nervously pacing up and down his hotel room. He is preparing for a meeting with some important clients who he is supposed to meet in the hotel lobby at 20:30.
He checks his clock radio sitting on a small cabinet next to his bed and sees that he has several hours to go before the meeting. He decides to have a quick nap. Since he only wants a quick nap he doesn’t bother getting undressed and just takes out his false teeth, kicks off his shoes and puts his glasses on the bedside table. He’s worn out from worrying so he falls asleep very quickly.
When he wakes up it’s dark. “Damn, must’ve overslept” he thought. Drowsily he turned to look at the bedside clock, struggling to focus through his tiredness. The clock said 20:15. The meeting was at 20:30 so he had to hurry. He managed to get ready quickly and he ran downstairs to the lobby. This whole proceedure took 5 minutes. When he got to the lobby a waitress came up to him asked
“Are you Frank Smith?”
“Yes” he replied.
“Well, the two gentlemen who you had arranged to meet here asked me to tell you that they were tired of waiting and have left”
Frank was amazed. He knew his clients were always obsessively punctual, never a minute too early or a minute too late. What could have happened?
How did Frank manage to miss the two clients?
