Feeding when out?

Just Me • Have a 4 year old daughter and a Newborn GLOW baby girl born 22/04/15..so in love 💕
How do you ladies feed baby when out? I went out yesterday for first time since having baby (she 14 days old today) and I ended up having to breastfeed sat on a toilet in a stinky cubicle for 35 mins and I felt so crap, the food I ordered came in that time and went freezing and had to be packed up and missed all the fun of being out with family because I was say in the toilets with a door that didn't even shut so I could even sit down after 15 mins because everyone kept opening the door and nearly whacking baby head (was tiny cubicle). I'm thinking of expressing and freezing it twice a day so I have a supply available for going out and then giving in bottle but don't wanna cause any confusion now she fully on breast (was expressing at first she wouldn't latch). Not confident enough yet to use a cover because still need two hands to feed lol
Advice ladies.
