A muscular man enters a bar and announces:
- A chocolate, otherwise ...
The bartender gets scared and serves him his chocolate. The muscular man, satisfied, goes away without paying. This scenario is repeated every day of the week.
After a week the bartender decides to react and not to prolong this intolerable situation.
The next day, the muscular man enters the bar and announces:
- A chocolate, otherwise ...
- Otherwise what ?
- Otherwise a tomato juice!
