No worries 
Yep, I do avoid movie theaters etc… because of the risk.
No, unfortunately as an academic I travel A LOT. I have a 30-45 minute room-check regime that I do in hotels (see below).
I don’t “worry” about bedbugs a set number of times a day. As part of my job and due to my professional experience, I am aware of them. If I am in a situation that has risk factors, I take appropriate precautions.
Don’t like it. Don’t like having guests in my home either. If I am a guest in another’s home, I try to discretely check for signs. If I am sleeping there, better believe i’ll check the bed/room (but not in the owner’s presence).
I have given this in a couple of other posts, but here is a summary of my travel regime again (i’m copying this from another post):
**If you are traveling, i would take measures to minimize the chance of picking them up. Any hotel can have bedbugs, even nice ones. You can pick up bedbugs anywhere, but you are far more likely to get them from a hotel than anywhere else.
Check your hotel online to see if there are any bedbug complaints. In the states, you can look up on bedbugregistry.com, i also use the various travel rating sites. As often as not, if you type the hotel name and “bedbug” into google, if there are complaints they will come up.
Don’t use a regular suitcase. I use a canvas duffel bag. When i get home, all my clothes and the bag are thrown immediately in the dryer for an hour on high to kill bugs and eggs.
If you must use a suitcase, bring a bag of food-grade diatomaceous earth with you (it must be food-grade, not from a swimming pool supply store - other kinds are inhalation dangers, and don’t inhale it in in any event!). When you pack to go home, sprinkle this liberally in the suitcase (and pockets) to help kill any hitchhikers (not guaranteed, but its something). Seal your suitcase in a plastic garbage bag on your way home. When you get home, unpack the bag directly into the dryer (see above) then immediately vacuum out the bag. It helps to scrub the bag with a brush to dislodge any eggs that may be in there.
When you check into your hotel room, put the bags in the tub until the room has been inspected. Bring along a flashlight and a magnifying glass. Strip the bed. Using the light and magnifier, check the mattress and boxspring carefully for bugs, skins, feces and eggs. Remove the headboard if possible and check behind it - this is a favorite spot. If you can’t remove the headboard, at least use the flashlight to see if anything is there. Check the junction of the walls and ceilings for bugs. Check behind pictures, mirrors etc… Don’t sit on couches etc… (or at least check them).
Do not unpack your bags into the dressers. Keep your bag elevated on the rack and live out of the bag. Even better, if you are using a duffel bag, keep it hung on the bathroom door hook. If i have to hang my clothes, i use my own wire hangers and hang them on the shower rod.
If you find bugs, make them move you. Not on the same floor! Bugs can move between rooms, or even up or down. I would demand to me moved to a different floor, at least 2 floors away (i.e., if i was on the 3rd floor, i would demand to be moved to the 1st or 5th - not the 2nd or 4th).**
