Allowances are never enough anywhere on the network Unless you stay in the hotel and get the discount. Isn't it the simple truth? And by principle $6US is an insult don't you agree? Better give me nothing. Then I can really say how cheap you really are. Better than giving me $6US and try to justify that it is enough. I don't buy it. Just plain cheap to pay anyone $6US for a night stop anywhere. Call a spade a spade!
