Because then you will never be out any money just to feed yourself on the road
Ok, sure but what would prevent someone from ordering the most expensive item on the menu every time. If you're out money from eating on the road, you're doing something wrong, perhaps you are going to too many fine dining restaurants.
Now, you might be one of those people who eat like a bird and can save a ton of the money you get for expenses
I can assure you at 280 lbs, I do not eat like a bird. On the road I eat the same as if I'm at home, so to do that I prepare and bring some with me and only eat a restaurant meal once a day, this is not an effort to save money, it's about controlling what's in my food. At home I go to an expensive restaurant once in awhile, so why would I do that on the road. I have a very hard time spending 9.00 on a beer when I know at home I can have the same beer from my fridge for 2.00, so I have water, sure I could order the beer and sometimes I do, but to me I don't enjoy being ripped off so as a consumer, I protest with my wallet. Same reason I won't buy the 20.00 burger and 3 fries from the hotel restaurant, I'll venture out and find a reasonable meal at a reasonable price.
That's why it is foolish to expend bargaining capital on anything beyond true realistic per diem
Which is why I said they set it to the max the CRA allows and the dollar amount is tied to the CRA limit, can't see that being a problem
