Why shouldn't I take a bottle of ginger ale?
Do you really like ginger ale?
Yes, I do. I've been drinking that kind of drink since my childhood.
Did you ask if you could have it first? If not, I highly think that you should take it. Put it back and then ask first.
I really really really really really really really really like ginger ale, but I don't have any money.
If the ginger ale doesn't belong to you and you have not purchased it then it is immoral and illegal to take it. You could end up getting arrested for theft if you take it.
