Radar hunting at banks

Is my situation unusual?

There's this certain branch of BMO I go to in Mississauga very frequently, and they are a branch that has a very high in and out cash volume. Anyways, the cash dispensers the tellers use are consistently loaded with brand new $5, $10, $20, $50 and $100s, and when I notice a note is maybe 100-200 notes away from the radar, and when I ask nicely, they are willing to press another 200 notes out of the machine until the radar comes, and all I'm obligated to exchange for is the radar note. (They just seem to return the notes to their drawers, they don't seem to make it like a big deal).

Is it just me, or is my bank branch being extra nice? I got a $20 from them last week that was #6662666, but unfortunately they didn't have the nice solid 6666666, I was told that they had only ordered that brick of 1000 brand new $20s.

They have even offered to order me bricks in any denomination I want without a service charge, and they tell me they don't mind if I end up returning them, as they would just recirculate them back to customers anyways.

However, they are strict on the $1000 notes policy. They won't give me one even if they have them.
