Room temp(RT) is usually somewhere between 73 and 77 degrees F or 23-25 degrees C. This also applies to metrologies where I work. 
We usually start temperature based experiments at RT which is 25 degrees C (Ambient is usually below that but the machine will equilibrate at a RT of 25 to keep things simple). Our climate chambers are sometimes held at RT which is 23-25 depending on which engineer is requesting the experiment.
Min you are talking about ambient temperature which is a very literal way to interpret RT but not very useful when trying to communicate between areas of the world. I wonder if there is a spec. around this...
Yes there is:

Temperature is not an acurate enough way to assure that values from different datasets will match, so pressure must be accounted for. The problem with NIST's definition as well as IUPAC's is that STP is always below ambient so that presents a problem for test equipment that is not enabled with some form of chiller. For this reason, we adhere to the rule of thumb of 25 degrees C being considered RT within a temp controled building.
I imagine that bars and pubs have mush less stringent controls and much less need for their, uh, datasets to match so RT is whatever the hell their place is kept at, wheather permitting.
