Need more customers, income and data

[DCPSHER]

I've reached max level and size of the shop.
The area is quite big, many shells, many goods, but all of the customers are easily served within 1 worker checkout and 3 self checkouts.
Prices are set correctly (according to +20-25% price guides).

Thanks for v1.0 jump function I can now jump on the shelf and count all customers. Usually it's about 20 at peak. It's okay for 3-5 level store, but not for 15+.

I want to feel the pressure of the lines and also have a good payout and account balance dynamic grow if everything is working properly.
One of my last achievements done was 100k farming and it took quite a long time. I stopped buying new goods to earn last 30k faster with full stock. Subjectively 70 to 80k farming time felt the same or even slower as growing from 0k to 10k balance at early levels.

I was taking cashout by myself sometimes and especially check if there are some total checks over 100$ and there were like 1 out of 50, smth like 120$ or 105$. So where are 200-500$ totals?
Maybe adding some expensive stuff may solve the problem, idk like whiskey bottle on lvl 15 for 80$ a bottle, not another color of soda for 1.5$.

And the last thing, I suggest that I heard a few times customers complaining about prices or goods. But they do it in English, not all players know it and can recognize it by ear. Personally I prefer to decrease the game sound level to 0-5%. So I don't get all that info at all. It would be great to have either subtitles of complains or like screens with customer reviews about prices or out-of-stock goods. Especially if that's the reason of some problems with income and customer density described above.

So, please, more expensive stuff, more clients and more info.
Thanks for the great game!
