Well, the thing about English is that it has several present tenses rather than one, unified present tense.
"A man walks into a bar . . . " is an example of the Present Simple tense, which can talk about things happening one time or repeatedly. For example: "the sky is blue". We know that the sky is not always blue, but that it is often and repeatedly blue.
The way that language influences perceptions of time have always fascinated me. For example, in English there is a lot of discussion about the verb "to be". It denotes that something always exists, like, "the universe is vast" as in, it is now vast, it has been vast for an unaccountably long time and will always be vast. Of course, it would be odd to find a language where entropy is denoted implicitly.
