"Could we have a table, please"
In a video lesson I was taking, the phrase, "¿Could we have a table, please?" was translated, ?Tienen una mesa, por favor?" Could you also say, "¿Podriamos una mesa, por favor?" Would the conditional tense be correct here? Thanks.
¿podríamos tener una mesa? is correct.
You could also simply say "somos dos" (o tres lo que soís) and arch an eyebrow?
The difference would be between "Do you have a table available?" and "Would we be able to get a table (at this time)?" Obviously, both of these questions lead to the same end.
