What is a global service fee?

Excuse me, could you please clarify what exactly is meant by a "global service fee"? Is it a type of charge that applies universally across different services or platforms? Is it a fee that customers are required to pay when using a specific service, regardless of their location? Or is it something else entirely? I'm trying to understand the concept and how it might impact users of cryptocurrency and financial services. Thank you for your help in clarifying this matter.
