How much do you need to spend to get the free $1 voucher to buy things from the bakery or the hot food area?

Supremetime gave the best answer! $1 voucher for every $20 spent on weekday. $50 spent on weekend.

It depends on date. Weekend will have a higher base to get and weekend day will be lower. Example you may get coupon if above 20 USD on weekdays but weekend will be above 50 USD only.

$1 voucher / Every $20 purchased.

For every $20 you get $1 card.
