Bruce Wayne 666

This is from Batman (1989) where Bruce Wayne is talking to Vicki Vale and Alexander Knox in a room in the Wayne Mansion.

During the conversation, Bruce Wayne gets interrupted by a wine steward who says:

Mr. Wayne, we need more champagne. Is that all right?

Bruce says: Sure. Go ahead.

Bruce says: How many cases? Six? Six?

Alexander Knox says: Six is good.

Bruce says: Six. Thanks

Subtle reference to the beast by the script writers. Here is one of the first drafts of the Batman movie script and no subtle 666 reference:

It must have been a final edit. I'm not surprised.

Coincidence theorist will think it's just a coincidence. To me, it was done on purpose by the script writers as a final last minute edit considering it wasn't in the first draft as I referenced above.
