I will tell you that the NY Metro leadership team has stated they are against covering the outlets because it is a passive aggressive way to deal with the issue. However, in extreme cases, they have approved this action because (and let's be real here) some people just cannot be reasoned with.
The person who posted the above adds:
If you are one of those people who uses Starbucks as their office, sits in a store for 8+ hours a day, putting all your files on a table, using a separate chair for your laptop case/ suitcase enjoying unlimited free refills with your Starbucks card, asking for cups of water and refuse to to move until you are good and ready all for the $1.85 you pay as "rent," then perhaps your actions will answer your questions [about covering the outlets].
I believe that Starbucks' "Just Say Yes" philosophy is responsible for people thinking they can park all day at Starbucks and use it as an office. Is it time to amend that to "Just Say Yes -- Within Reason"? | Jump to the second page of comments.
