I'm talking to an airport attendant helping me around the airport because of my broken leg. I say:<br/><br/>You could just leave me at the gate and I'll be okay from there. OR<br/><br/>You can just leave me at the gate and I'll be okay from there.<br/><br/>Should it be could because it's a suggestion? But can sounds more certain, so I'm not sure which one to use.<br/><br/>Thank you!
