My mom, who will be 72 in September, has been carded for alcohol at Walmart.

She does not ask store management why she was carded.
She does not give the cashier a hard time.
She is not embarrassed to show her ID.
She does not complain about it.
She does not feel that it is disrespectful to card senior citizens.

She just shows the cashier her ID.

She realizes that there is a reason why the store is asking for her ID.
