Sorry, but no. And few are cheaper than I am.
M&IE, by it's very definition, includes Meals and Incidental Expenses (such as van driver tips), so you cannot claim tips as a deduction on your taxes, in spite of what EZ Perdiem may tell you. In fact, the IRS tells you clearly that you can only claim tips towards something you are paying for (if you pay for a taxi and don't get reimbursed by the company, for example).
Personally, I never tip a driver, unless he/she goes above and beyond to help me. They get a paycheck just like we do. I've probably only tipped about $4 in the past year.
There are those who claim internet and cell phone costs, but personally, I shy away from that, even though it's legal. Why? Too much record keeping to keep it legal. If I pick up one single turn per year which credits 4 hours, I will make more money than all the cell phone and internet deductions combined will ever net me on taxes. Too easy.
