“Have you ever walked into a bar and the bartender asks for and holds your credit card while opening a tab? This is a very negative and I submit it is often poor business practice. In this example, one of the earliest interactions with a customer is to signal a lack of trust. The bartender is suggesting the customer will leave without paying. It would be one thing if the bar was making the customer’s life easier so when they were done they could simply walk out effortlessly paying the bill but that is not the typical case. I understand some bars have issues with people “dining and dashing”, so a bar owner has to weigh the pros and cons – but few realize there are cons that should be deeply considered.“
