A man walked into a bar and ordered

A man walked into a bar and ordered a twelve-year-old scotch.

Believing that the customer would not be able to tell the difference, the bartender poured him a shot of cheap three-year-old house scotch.

The man took a sip before spitting it out on the bar.

“I’m not drinking this!” he complained.

“This is cheap three-year-old scotch.

Now give me the good twelve-year-old scotch that I asked for!”

Still looking to cut corners, the bartender poured him a shot of a moderate six-year-old scotch.

The man took a sip before once again spitting it out on the bar.

“This is just a six-year-old scotch,” he moaned.

“I’m not paying for this!

Now will you give me the twelve-year-old scotch I ordered?”
