Researchers writing in Health Affairs Scholar found that backing for gun limits at bars and similar sites is common until modest fees to enforce them appear. With no cost, 56 to 74 percent of a sample matching voting-eligible Americans supported the limits, and over 65 percent did so for large sites.

A yearly 100-dollar charge per taxpayer left majority support only for rules covering felons, intoxicated patrons or people with alcohol convictions, and only at large sites. Coverage in the UCLA Anderson Review said attaching a price makes voters reluctant even on public safety.
