Answer:
No, since he didn't pierce the corporate veil. He personally didn't mix personal activities with business activities. Piercing the corporate veil refers to actions taken by the owners or shareholders themselves, not the employees.
Explanation:
Smith Services Inc. was a limited liability company, and as such was a separate legal entity from its sole owner Tony Smith. The problem is that since it was a single member LLC, limited liability might or might not apply. The IRS directly disregards single member LLCs and directly taxes the owner, but state laws generally protect the owner's personal assets from any of the company's liabilities.
A state court will find Tony Smith personally liable if he pierced the corporate veil, i.e. if he mixed personal matters with the company's matters, then a court might rule against limited liability.
In this case, Smith's best argument would be that he personally didn't pierce the corporate veil by charging fuel on Laker Express gas station. His employees did charge fuel, but apparently he didn't. The corporate veil doctrine is invoked when owners blur the distinction between the company and themselves. Courts only impose personal liabilities to the parties that acted wrongfully, not to innocent parties.
