Why offer delivery of it isn't possible?

Today not the 1st time we've ordered for delivery in the last while from the Lynnwood Glen Gables store to only be left waiting (we live 5 mins from the store). When eventually following up, usually after an hour, to be informed the store doesn't have drivers available? Why offer delivery then? What's worse when the order eventually does gets delivered, it is ice cold. Nah. You've lost a customer here. This is a recent development but if this is how unreliable delivery orders are we'll rather support any of the other options (of which there are plenty) in the area.
