Osechi-Buro: The Second Course

The detective gathered all the people involved in the banquet hall of the hot spring inn, which had been isolated by a blizzard, and cleared his throat.
Before I reveal my deduction, I must ask you all: Where are we, and what time is it? Yes, we are at a hot spring inn, and it is New Year's. What are we eating? Yes, Osechi. Since we are welcoming the Toshigami, we do not use knives or cook. Running water is also considered bad luck, so there is no washing dishes, no laundry, and no baths.
1. New Year's Day: Osechi is available, but there is no bath.
2. Any other time: There is no Osechi, but there is a bath.
The detective paused dramatically.
Are you following me? Osechi and the bath—these two never show themselves at the same time. Has anyone here seen them together? I thought not. That is because they are the same person.
Ridiculous. I went through all the trouble of buying tickets for the comedy duo 'Osechi-Buro' just to come all the way here!

Is this satisfactory?
The impromptu solo comedian 'Great Detective' gave a wink to the manager. Thanks to that, no one mentioned the broken bath, the food that never arrived, or the attraction that never showed up.

Because they were all snow sculptures displayed in the banquet hall.

I added the final line after receiving feedback that it was cold ⛄️
