There are two sentences that I'd like to fully understand.
Only 30 years ago, it was almost impossible to come across a family that had a car, but Korea has changed beyond all recognition and cars have become very common. More often than not, one family 'will' have 2 or 3 cars.
I can't understand why 'will' is used. What if I use just 'has' instead of 'will have'? All I know about how to use 'will' is 'voluntarily action' or 'prediction'. Could you help me understand the difference 'will' and 'will have' above sentence?
Once I'm done with my banking, everyone wishes me a good day and someone 'will' always be on hand to hold the door open when I leave.
Similarly, I'd also like to know the difference 'someone is always on hand' and 'someone will always be on hand'. For me, it is much easier way that I use the former than the latter.
Thanks in advance.
