We arrived for dinner at 6.20pm and read the board outside which advertised dinner specials upto 6.30pm.
We immediately ordered the special from the waitress (the place was not busy). She seemed unaware that there was a special - went and looked and came back to tell us it was almost 6.30pm. She told us we couldn't have the special - we were given neither apology nor explanation.
In a 2 month trip, this was an outstanding incident - we found Australians to be very helpful and obliging - as they were in the next door Pizza/Pasta Restaurant where we took our dinner business.
