Below is the answer I received from TABC when I asked about a similar situation. If the bar operator was NOT at their permanent location I imagine the same would apply.rotor wrote:A question for the group slightly off topic. Went to a charity dinner over the weekend and they had a bar set up ( for pay bar) far away from the entrance and they had a 51% sign. No sign at the door and the 51% sign was a paper print taped to the wall. I was not carrying anyhow as I was going to partake in the beer but I thought to myself what the legality of carry would be since there was no sign at the door, only next to the bar set up.
For question #2, a temporary permit was issued for that function and a
blue sign should have been posted. XXXXXXXXX itself is required
to have (51%) signs posted at its permanent licensed location. However,
411.204 of the government code, doesn't require temporary permits to
have 51% signs posted, only the blue sign is required, regardless of
sales. We will remind our temporary applicants that only the blue sign
is required.
