User: hi id like to buy a ticket for bad boys for life
Assistant: hi thank you when would you like to see that?
User: 12pm would be great
Assistant: would you like to see that in IMAX or regular
User: IMAX is good
Assistant: and would you prefer standard or 3d?
User: let's do standard
Assistant: thanks, it's $439 for that selection
User: sounds a bit high, but ok. actually, let's change it from standard to 3d
Assistant: ok, 3d is $3.
User: wow that's a bit cheaper. why's that?
Assistant: it's the $3 3D special.
User: oh, that makes sense. well, i'll definitel go for the 3d then, even though i don't really like it.
Assistant: it's certainly different. is there any other tickets you'd like?
