The update as of 2020-11-26.
It is an experience to shut eyelids in for example some supermarket and to try to navigate, to orient with no human assistant. Even when the price, unit, mass, piece tags are accessible and scannable by some smart device. Even when there is a voice assistant over the shelves in some supermarket. Even when some products have texts via Braille writing above packages. Even when travelling in shopping tour among supermarkets and other ones after shutting eyelids.

Це досвід заплюшити повіки у наприклад деякому супермаркеті універкрамі та намагатися навігувати, орієнтуватися з не людяним асистентом або без людини асистента. Навіть коли ціни, одиниці, маси, шматочки етикетки, ярлика, бирки, талона, наклейки є доступними і навіть зчитуємими деякими розумними пристроями. Навіть коли існує голосовий помічник над полицями у деякому супермаркеті універкрамі. Навіть коли деякі продукти мають написи у стилі Брайлля поверх пакування. Навіть коли мандрувати у покупельній мандрівці між супермаркетами універкрамами універмагами і іншими після заплющення повік.

Деякі вендінг машини не дають підробок з огляду і не лише на декілька нещодавніх обмежень, хоча вони мабуть натякають на легкість додання виконання тих обмежень як фактор опісля.
Some vending machines do not give a sham according to several recent limitations, though they probably imply the easiness of addition of such implementation of those limitations as a factor aposteriori.
