Having gone to O Treo as many times as I had gone to Pink Street (see O Trevo: My Favorite Bar, Restaurant, Hangout in Lisbon & Pink Street: Again & Again) , I decided to branch out and go past the Baixa-Chiado metro station (see Metro Lisbon? TPOL Leaves the Neighborhood for Cafe) to see what else was available. Inevitably, I ended up in another stand up bar where a glass of wine and an espresso were 2.70 euros. I went outside and sat at one of the restaurant tables. The waiter said I technically could not sit there because wine outside is more than double the price of wine inside. I laughed and he left me alone.
Walking around more, I found another stand up bar and this time was told I could sit outside and order food. 
After a few more stops, I started to feel the tap to pay guilt. Instead of abusing my credit card further, I found the nearest grocery store and went home. For 5 euros a bottle, I could drink vino verde until I was green in the face.
Little did I know that this last hangover would lead to freedom from American consumerism (see Tap to Pay? Sorry, Cash Only for Me).
