Drop and go royal mail

A popular phrase!

"Drop and go" is a colloquialism used in the UK, particularly in the context of Royal Mail, to refer to the process of posting a letter or parcel at a postbox or post office without waiting for a confirmation or receipt.

In other words, you simply "drop" your mail into the postbox or hand it over to the post office staff, and then "go" on your way, without waiting for any further action or acknowledgement.

This phrase is often used to convey a sense of convenience and efficiency, as it allows you to quickly and easily dispatch your mail without having to wait in line or fill out any additional forms.
