Marketing Gimmick or Misrepresentation?

"INTERNATIONAL BEER PROMOTION. Daily. Time : 11:00 a.m. - 12:00 a.m."

Whey you walk past this poster and look at their promotion, what do you think that they were promoting and what is the duration of the promotion?

We were staying at E&O during the past weekend for a short break and I came across this at one of their outlet. My wife was looking at me and said, "Wah. You happy lor! International beer promotion and some more whole day!" Honestly, I was excited looking at the range of international beer that was displayed at the poster and the whole day promotion period.

So at 4p.m. we happily walked into this outlet and ordered our snack since they have their burger promotion. Fortunately, I am sober enough to ask what kind of international beer do they offer and at what promotional price? Shocking as it sound to me, this was the waitress answer...

Me: "So, you have beer promotion right ?"
She: "No sir. Not now. Only happy hour."
Me : "Huh? Happy hour? What time is your happy hour?"
She: "5 p.m. to 8 p.m."
Me: "But your poster outside says "11:00 a.m. to 12:00 a.m. daily"
She: "Oh...That is our opening hours sir."
Me: "Huh? Eerrr...ok...so what kinda of international beer do you offer?"
She: "On the menu sir. Tiger, Guiness and Kilkenny"
Me: "Huh? That's all?"
She: "Yes sir."

At this point in time, I am really not in the mood to argue with her and I don't intend to spoilt my holiday over a glass of beer. But what happened to the Corona, Asahi, Leffe that were in the poster?

Wife: "How about your burger promotion?"
She: "Oh. That we have the whole day."
Me: "Huh????"

Two seemingly similar messages in the same poster but with different results. So, is this just a marketing gimmick, pure oversight or gross misrepresentation.

Anyway, since by the time, the burger arrived, it was already 4:30p.m., I just waited till 5:05 p.m. (just to be certain) before I ordered my Kilkenny draft at happy hour price. A holiday will be a holiday and nothing is gonna spoilt it.
