I haven't heard anything from the bank or users that your kind of spending is a problem. I've heard they look for big spenders that buy at Simon or obvious online gift cards in large quantities. For one thing, that card reports your monthly spend to your personal side of credit bureaus anyhow. I believe most business owners do mix personal spend on some business cards, but not corporate cards, but even the corporate cards and their companies that issue them to employees expect dining, transportation (fuel) and other type of expenses since it's all a part of doing business. Some small business owners even place certain utility expenses on business cards because they are permitted by the IRS to use a certain amount of electric, internet, and so forth in expenses from their home businesses. What about entertaining clients in the home business which would most certainly include groceries, catering, and some retail stores also sell office supply (look at Walmart or Amazon). The lesson from the previous poster above mine is a good example and that's good they admitted it to help others.
