Denny's Server Training Practice Test

The correct answer indicates that there is no specific day offering a 10% discount on all menu items. This suggests that the restaurant does not have a regular promotional discount day as part of its offerings.

In a typical restaurant setting, discounts may be offered on specific days to encourage customer visits or to promote certain menu items. However, in this situation, it appears that such a policy does not exist, hence why "None" is the correct choice. The other options imply that specific days are designated for discounts, which is not the case here, leading to the conclusion that a day with a 10% discount does not occur at all.
