This is the way it's going in many places due to soaring costs etc... what's called "shrinkflation", and it's an insult when prices slowly creep up and portion size contracts. Got to the point for me where I simple don't got out to eat anymore, cook from scratch at home with the wife... healthier, better quality, control over what goes in, and ultimately cheaper over the month. Still go out for a beer once a week, but beer prices aren't what they were either, as getting pricey in bars for a bottle, or 5, when out on the lash.
The thing is, many businesses price themselves out of the market through greed and sentiment/confidence of normal folk isn't high right now... which leads to saving and thrift/deal and bargain hunting. Many people now refuse to buy anything unless it's discounted or a 2 for 1 offer etc. (even bulk-buying at Makro is preferable), with brand loyalty out the window... and add to that most government's now are on a tax grab, hardly suprising we find ourselves in this situation of suppressed economies and stagnation.
