It is probably not technically correct to do so, but you will definitely find many people using "the", even when there is a number of identical objects involved. This is particularly likely if it can already be assumed that the person to whom you are speaking has some knowledge of the likely location, or if the location can be easily determined due to some other factor (being in plain sight, for example).

As an example, some might say "your wallet is on the table", knowing full well that there might be several (possibly identical) tables, because either it is in plain sight or because the owner of the wallet already knows which table they were near to and therefore where they left it.

This can (and often does) lead to confusion and prolonged searching, but it is something you will encounter regardless.
