Those NHS ads - "I will choose" etc

[UnquietDad]

"I will choose a hospital near my home" and all those others on buses, billboards etc.

Just doesn't sound right - "I will". Surely "I want to"?

or 'i'll be lucky if i get a hospital near my home'

Not paid any attention to ads.
But doesn't 'I want to' suggest that 'I may not be able to.
'I will' suggests that its going to happen...
(apols for grammar etc....)

what on earth are they trying to say?

I can see the difference, but it seems an odd way of saying it.
