💵
Tipping is not optional
Service staff earn below minimum wage — tips make up the bulk of their income. 18–20% at restaurants is standard, not generous. Not tipping is considered rude and causes real financial harm.
🌡️
Fahrenheit, not Celsius
Houston in June-July is 94–97°F (34–36°C) with high humidity — heat index hits 105–112°F. When someone says "it's 100 degrees," that's extremely hot, not boiling. Quick conversion: subtract 32, divide by 1.8 for Celsius.
🚗
Houston is not walkable
Outside specific neighborhoods (Downtown, Midtown, Montrose, Heights), distances are car-only. METRORail Red Line covers Downtown↔Med Center↔NRG Stadium. Everywhere else, use rideshare or rent a car.
💧
Humidity is the killer
Houston feels much hotter than the temperature suggests because of 70–85% humidity. You will sweat through clothes within minutes outdoors. AC is everywhere — use it. Drink twice the water you think you need.
🥤
Free refills are real
Soft drinks come with unlimited free refills at almost every American restaurant. You don't need to ask — just drink your soda and your server will top it up. This is completely normal.
🍖
How to order BBQ
At Texas BBQ joints (Truth BBQ, Killen's), you order by weight at a counter — "half a pound of brisket, please." The meat is sliced in front of you. Sauces are on the side. Eat with your hands — it's expected.
🌮
Tex-Mex vs Mexican
Tex-Mex (yellow cheese, fajitas, frozen margaritas) is its own cuisine — different from interior Mexican (mole, mezcal, soft tortillas). Houston has the best of both. The fajita was invented at Ninfa's on Navigation in 1973.
🍺
Always carry your passport
US bars and venues card everyone who looks under 40. You need government-issued photo ID to buy alcohol. Your passport is safest. Some venues don't accept foreign driving licences.
💬
"How are you?" is a greeting
When an American cashier or server says "Hi, how are you?" they expect "Good, thanks!" — not an actual account of your wellbeing. It's a greeting, not a genuine enquiry. Respond with "Good, thanks — how are you?"
💊
Healthcare is very expensive
A hospital visit in the US without insurance costs thousands of dollars. The Texas Medical Center is the world's largest medical complex — but it's still expensive. Buy comprehensive travel insurance before you travel. This is non-negotiable.
🌐
Spanish is widely spoken
Houston is roughly 45% Hispanic — Spanish is the city's second language and you'll hear it constantly. In East End, Bellaire's eastern stretch, and many service settings, Spanish is the primary language. A few words go a long way.
🦟
Mosquitoes everywhere
Houston is a Gulf Coast city with bayous and standing water — mosquitoes are real. Bring DEET-based repellent. They peak at dusk and around any body of water. Indoor AC kills them off — they're an outdoor problem only.
