Unfortunately, may people assume that someone else will know where the AED is or that someone else will respond. This results in a false sense of security leaving employees with the impression that someone in the workplace will be qualified and able to respond, when that is clearly not the case,
If you are working in a new location or begin frequenting a certain establishment, always locate the nearest available AED if there is one. AED machines can be hard to find, but in most public places they are located where a fire extinguisher would be: near an exit, bathroom, break room or even at a front desk. if you can't locate the AED; ask the manager or supervisor where the nearest AED and First Aid kit is located.
It is always good to be prepared.
