Alcohol vendors asked Prime Minister Prayut Chan-ocha on Monday to allow for takeaway and delivery options instead of a complete ban on alcohol sales.
Public Health Minister Anutin Charnvirakul said that the request would not be considered.
Many provinces, including Bangkok, have extended its alcohol prohibition period until the end of April to stop people from breaking curfew.
Anutin said it was still too risky to allow the sale of alcohol. Without a vaccine, there is still the possibility of a second wave of infections, he said.
He said that the sales of alcohol would encourage people to congregate which could lead to a resurgence in new cases.
The vendors say, however, that a continue of the ban would result in staff redundancies.
