Good maths

While waiting for shuyi one morning at T2, I decided to have a cuppa at Tosto. So get this. The americana cost $5.20. When I was served the coffee at my table, the helpful lady asked

'do you want a sandwich to go with that?'

Now, $5.20 is plenty expensive for a simple cup of coffee already. I try to refrain from buying expensive coffee outside as I have my own espresso maker at home and a cup works out to be around 60 cents. So I refused. But the lady dropped the killa proposal.

'we're on offer. coffee + sandwich = $5'

Man! That is some trippy math. Load me up with sandwich lady! No wonder she looked so confident that I'll have some sandwich.
