Village Inn Restaurants review: dishonest business

The food may be good for breakfast but definitely not for dinner. As I can tell the business was very slow with two tables served when I came in at 6:00 PM. I give 2 stars to their food but 0 star for your reputation. They had promotion in Jun, 2019 with two $5 bonus cards when purchasing $30 gift card. I was told that bonus cards can be used like gift card or cash in any village inns when purchasing it. When I come back with bonus card but was told another way - it cannot be used with any offers such as kids meal free on Monday / Tuesday or free pie on Wednesday. So bonus cards are really treated as coupon that you can readily get or receive it all the time. That would be OK if they should make it clear upfront. I don't like this dishonest way to do business. Do you?
