I do not gamble but...
Different people enjoy different types of entertainment.
Some golf, bowl, see movies in a theatre, knit, or buy antiques.
It makes no difference to me what other people do with their money.
Regarding the payment of a $3 purchase with a credit card...
Credit card rewards programs incentivize this.
My wife has companion status with her Southwest Air credit card rewards program.
That results in me flying for free (with her) about twelve times a year.
In the business from which I retired, transaction speed was critically important.
It was determined that a cashless (credit card or debit card) transaction was faster than a cash transaction.
Customers fiddling with their coins and bills took longer than those who simply presented their card.
