not sure your last statement has any point really, at least not one that would concern you...they sell alcohol to whoever wants to buy it...they focus on everyone, but obviously on certain groups if there are particular occasions going on, such as perhaps the world cup will be aimed mainly at lager and men i assume, so offers an gieaways will reflect that...but really its generally just whatver and whoever
you could ask if they do instore promotions much...you know like taster sessions to promote a new drink, with balloons, banners and t-shirts etc
i dont see any harm in asking about hours..you could ask about when rather than how many
