Tesco may deliver.
But do they do bacon and onions to go with it?
On a more serious note how quickly do they do liver?
What if you need it now?
And might you as well do the rest of your shopping while you are picking it up in your car?
Which means that last night's delivery was a waste of time, effort and resources!
As for moving closer to tescos:
What if that means moving further away from your doctors.
And the leisure centre where you get the excercise you need on doctor's orders.
And your partner's work.
And all the other shops you need.
Perhaps in your ideal world we all live in a 10 mile high needle thin tower block.
And shop, work, and access all the other facilities we need in an adjoining one.
And all live within 5 minutes walk of everything we need.
If we ignore the 10 mile vertical tram ride we need to take in each tower block.
But in the real world things don't work like that.
PS note that the vertical tram would have to stop every ten foot or so.
If it stopped on every tenth floor it wouldn't work would it.
Certainly not from a disabled friendly point of view.
Bit like the Nottingham tram.
Which, despite being so much faster than a bus.
Can't stop as frequently.
