Why don't some hotel restaurants have snow beer?

The sales staff of our Snowflake Company clearly tell you that all the places you go are closed by other brands of beer, which is the so-called wine supply (only one brand of beer can be supplied), and there are also many venues signed by Snowflake. You can pay attention. For red wine and white wine, this requires beer companies to invest considerable market expenses according to the sales situation of stores. Anything else you want to know, please add me QQ.
