Groundhog Day

I wrote this last Friday, and I will explain it in more details because of what happened today.

Last Friday
I went to a butcher's with my wee one. We were the only customer, and there were 3 butchers in the shop. G came over and served me. D was wandering about in the shop for the reason that I didn't know. P was behind the counter sorting out meats on the display table.
P walked past in front of me and said "Hello".
So, I said "Hello" back to him.
Then, after a while, he was behind the counter a few yards away from me, and said "Nice day today" to me.
So, I said something back to him. (See the link.)

This Friday
I went to the butcher's alone. I was the only customer, and there were 3 butchers in the shop.
G came over and served me. D was walking in and out of the shop sorting out signs. P was behind the counter talking on a mobile and soon hang up.
P walked past in front of me and said "Hello".
So, I said "Hello" back to him.
The after a while, he was behind the counter a few yards away from me, and said "Nice day today" to me.
So, I said "Yeah, nice day, indeed".

And I freaked out when remembering the last week's episode.

There are some more butchers who work there, and all of them seem not having regular shifts. Of course there are some differences in details, but... it was weird. Very weird.

Should I go to the shop on Friday next week?
