Totally agree, and definitely stress that this is not the norm with this job.
A number of years back, I had a client in the same situation but my advice went through one ear and out the other. After I finished his return for the year, he went back to his new employer and told 5 of his friends about taking mileage & meals.
When they traveled all the way to my office at the time, they left without taking the mileage & meals, but they gained about an hours worth of tax education on the subject of commuting. Why an hour? Thats about how long it took for them to get that just because you work at the same place doesnt mean that you get the same deductions as all of your friends!
