Sections 20 and 21 are new provisions in Irish law which respond quickly to a recent disturbing trend in drink retailing, namely, the promotion of a particular premises, product or brand by irresponsible special offers and discounts such as "all you can drink" challenges for a fixed sum admission price. We seem to be moving from happy hours to nightmare nights. These provisions refer to persons on a licensed premises consuming intoxicating liquor to an excessive extent, as referred to in section 21(1)(a). This may have to be extended to include persons likely to be attracted to licensed premises by promotion. In addition, since there is no statutory definition of what is excessive, it might be helpful to broaden the definition of what is unacceptable to include, for example, the consumption of intoxicants which, in the opinion of the court, is excessive, unreasonable or unhealthy.
