As you had a look through the supermarket you just entered, you saw some shelves that they just added as you could feel a heavy feeling of frozen air, and see the temperature in the store increase from inside. While taking a look, you saw that the employees were now wearing longer sleeves, and scarves.
This could mean that the season is now Winter as you saw that the snowflakes on the side of the shelves that had multiple products that you would be interested in buying while you were still inside, and saw that the snowflakes were different. The shelves had white snowflakes, red snowflakes, purple snowflakes, and pink snowflakes as you saw how different they were. Seeing the aisles in front of you, means you had about 4 hours to check out the aisles before the store could close.
