I often go to Wendy's or Subway for lunch. I used to get a soda which costs between $1-2. Recently I started filling up my reusable water bottle up and bringing it with me. It's healthier to drink water and it saves me about $30 a month. If I go to a sit-down restaurant I'll order a soda, but for fast-food places I bring the water bottle.Sometimes I'll bring a banana too (healthier and cheaper than fries or chips). The people working there never care, even though they probably think I'm weird!
