Weird Dutch math

There is a grocery store in NL named Hoogvliet (pronounced hoge-vleet) that I frequent because it's noticeably bigger than the Albert Heijn (pronounced albert hine) near our apartment and not as far a walk as the Jumbo (pronounced yumbo) which is even bigger.

Albert Heijn has a member card like many grocery stores do in the states. It's free to get and using it gives you discounts on specific items in the store. Hoogvliet and Jumbo offer their sales prices to anyone, no card needed. Hoogvliet DOES have a card but I haven't figured out what it's actually for. I got it because the cashier once asked me if I had one. Then I used it and noticed I was charged about 10% of my total the next time I was there. I tried to ask customer service what the card was for and the woman who was working there at the time didn't speak English fluently enough for me to quite understand how it worked. So, I don't use it any more... shocking.

Any way, there have been a couple of incidents at Hooglviet that have me scratching my head.

1) Just last weekend hubs and I were there together buying items for Sunday breakfast. We had picked out 2 croissants. When we get to the register the cashier tells us that 2 croissants cost €1.10 but if we get 4 croissants it will only cost €1. Huh? I didn't really want 4 because I didn't think we'd eat the other 2. The bakery section uses bags with perforations in them which lets air into the bag and turns whatever baked item you purchased into a rock after a couple of days. (Note: put them in something truly airtight and they will be good for a few more days) But, hubs went back and got 2 more croissants. The cashier was proud of herself "It cost you ten cents less and you get twice as many croissants". Um... k. You can't just charge me for 4 even though I only purchased 2? The woman in line behind us was so intrigued by this that she actually left the line to go get 4 croissants.

2) The store has eggs sitting "loose" for lack of a better word. They are in flats of about 36, stacked 1 on top of the other, with empty cartons that hold 6 or 10 eggs sitting beneath. (As a general rule, a dozen eggs just isn't a thing here). 6 eggs cost  €1.71 and 10 eggs cost €2.46. So, if you want 12 eggs it will cost €1 more than buying 10 eggs.

Loose eggs at Hoogvliet. "Doos" = box. "Stuks" = pieces

Now, the 6 egg cartons are actually dozen cartons perforated in the middle, and the first time I bought eggs there I picked up 1 carton like that. When I got to the register I was charged €3.42 because they literally scan the barcode on each 6 count carton (even though the cartons are attached to each other). I was NOT happy.

Often the 10 count boxes are gone, and I certainly don't want to be charged an extra euro any more just for 2 more eggs. So, 1 time I dared to ask an employee if they had any more 10 count boxes. You'd have thought I asked him to donate a kidney. He walks off without saying much to me, I followed, just in case that's what I was supposed to do. He walks to the complete opposite side of the store from where the loose eggs are and hands me a 10-count box already filled with eggs and then storms off. I had visions of Squidward from Spongebob Squarepants saying "He made me provide excellent service!"
