first of all people who are rude or have an attitude towards a waiter or any other working person are "sub-humans" to me (except if the waiter or the working person is rude too). I literally broke up with a girl because she was rude to waiters :P

Back to our subject now! My biggest fear is the following that you mentioned

On the other hand, if you lose your job or something similar you better look for a source of money real quick.

That i try to avoid overdoing something like waste money on drinks, delivery, food at restaurants, cinema, expensive clothes etc etc. It's not that i don't like them but if you really think about it most of these things aren't really necessary, it's more like an illusion of happiness. Thus i try be very careful with my spending but at the same time i try to keep a balance. For example when the Avengers came out (all of them) i went to the cinema to watch them but only these films. another example: i have 2 jackets one more light and one for more extreme temperatures. I won't go and buy another one till one of these 2 is worn out.

Also 2 other things

1. check if the bid-bot you are paying for promoting the post has a good return in your money. A couple of months ago that i did a bit of research in that matter showed me that mostly anyone using these services losses money. (i don't know if things change now but just informing you cause it's very relevant to your post)
2. Is the TV-Show girl beautiful? :P
