The item comes with a free coffee redemption coupon at a cafe.
A cup of coffee at the cafe costs $1.80.
She used the voucher at the cafe but decided to opt for a set meal which comes with toast, two eggs and a cup of coffee for $4.80.
The staff told her he didn't know how to key in the order for the voucher and the upgrade. He asked her to order the toast and eggs separately. The toast costs $1.80 and the two eggs cost $1.60.
