Animals are not allowed [people]

Animals are not allowed on restaurants is a sketch by artist and illustrator Artmagenta
On the restaurant:
The restaurant has a pleasant atmosphere, but today it was unusually messy.

I just had a cup of coffee and a pastry.

The two ladies in the foreground complained about the coffee. It was too bitter.

Behind the ladies sat a couple, the lady in the red dress. The man frightened her with horrific war stories.

A cat snuck into the restaurant. Animals are not permitted

 A waiter had problems with his balance.
